 Setup
 =====
 
 
 Setting up the application
 --------------------------
 
 First You'll ned to create RhodeCode config file. Run the following command 
 to do this
 
 ::
  
  paster make-config RhodeCode production.ini
 
 - This will create `production.ini` config inside the directory
   this config contains various settings for RhodeCode, e.g proxy port, 
   email settings, usage of static files, cache, celery settings and logging.
 
 
 
 Next we need to create the database.
 
 ::
 
  paster setup-app production.ini
 
 - This command will create all needed tables and an admin account. 
   When asked for a path You can either use a new location of one with already 
   existing ones. RhodeCode will simply add all new found repositories to 
   it's database. Also make sure You specify correct path to repositories.
 - Remember that the given path for mercurial_ repositories must be write 
   accessible for the application. It's very important since RhodeCode web 
   interface will work even without such an access but, when trying to do a 
   push it'll eventually fail with permission denied errors. 
 
 You are ready to use rhodecode, to run it simply execute
 
 ::
  
  paster serve production.ini
  
 - This command runs the RhodeCode server the app should be available at the 
   127.0.0.1:5000. This ip and port is configurable via the production.ini 
   file created in previous step
 - Use admin account you created to login.
 - Default permissions on each repository is read, and owner is admin. So 
   remember to update these if needed. In the admin panel You can toggle ldap,
   anonymous, permissions settings. As well as edit more advanced options on 
   users and repositories
   
 Using RhodeCode with SSH
 ------------------------
 
 RhodeCode repository structures are kept in directories with the same name 
 as the project, when using repository groups, each group is a a subdirectory.
 This will allow You to use ssh for accessing repositories quite easy. There
 are some exceptions when using ssh for accessing repositories.
 
 You have to make sure that the webserver as well as the ssh users have unix
 permission for directories. Secondly when using ssh rhodecode will not 
 authenticate those requests and permissions set by the web interface will not
 work on the repositories accessed via ssh. There is a solution to this to use 
 auth hooks, that connects to rhodecode db, and runs check functions for
 permissions.
 
 TODO: post more info on this !
 
 if Your main directory (the same as set in RhodeCode settings) is set to
 for example `\home\hg` and repository You are using is `rhodecode`
 
 The command runned should look like this::
  hg clone ssh://[e-mail]/home/hg/rhodecode
  
 Using external tools such as mercurial server or using ssh key based auth is
 fully supported.
     
 Setting up Whoosh full text search
 ----------------------------------
 
 Starting from version 1.1 whoosh index can be build using paster command.
 You have to specify the config file that stores location of index, and
 location of repositories (`--repo-location`). Starting from version 1.2 it is 
 also possible to specify a comma separated list of repositories (`--index-only`)
 to build index only on chooses repositories skipping any other found in repos
 location
 
 There is possible also to pass `-f` to the options
 to enable full index rebuild. Without that indexing will run always in in
 incremental mode.
 
 incremental mode::
 
  paster make-index production.ini --repo-location=<location for repos> 
 
 
 
 for full index rebuild You can use::
 
  paster make-index production.ini -f --repo-location=<location for repos>
 
 
 building index just for chosen repositories is possible with such command::
  
  paster make-index production.ini --repo-location=<location for repos> --index-only=vcs,rhodecode
 
 
 In order to do periodical index builds and keep Your index always up to date.
 It's recommended to do a crontab entry for incremental indexing. 
 An example entry might look like this
 
 ::
  
  /path/to/python/bin/paster /path/to/rhodecode/production.ini --repo-location=<location for repos> 
   
 When using incremental (default) mode whoosh will check last modification date 
 of each file and add it to reindex if newer file is available. Also indexing 
 daemon checks for removed files and removes them from index. 
 
 Sometime You might want to rebuild index from scratch. You can do that using 
 the `-f` flag passed to paster command or, in admin panel You can check 
 `build from scratch` flag.
 
 
 Setting up LDAP support
 -----------------------
 
 RhodeCode starting from version 1.1 supports ldap authentication. In order
-to use ldap, You have to install python-ldap package. This package is available
+to use LDAP, You have to install python-ldap_ package. This package is available
 via pypi, so You can install it by running
 
 ::
 
  easy_install python-ldap
  
 ::
 
  pip install python-ldap
 
 .. note::
    python-ldap requires some certain libs on Your system, so before installing 
    it check that You have at least `openldap`, and `sasl` libraries.
 
-ldap settings are located in admin->ldap section,
+LDAP settings are located in admin->ldap section,
+
+This is a typical LDAP setup::
+
+ Connection settings
+ Enable LDAP          = checked
+ Host                 = host.example.org
+ Port                 = 389
+ Account              = <account>
+ Password             = <password>
+ Enable LDAPS         = checked
+ Certificate Checks   = DEMAND
+
+ Search settings
+ Base DN              = CN=users,DC=host,DC=example,DC=org
+ LDAP Filter          = (&(objectClass=user)(!(objectClass=computer)))
+ LDAP Search Scope    = SUBTREE
 
-Here's a typical ldap setup::
+ Attribute mappings
+ Login Attribute      = uid
+ First Name Attribute = firstName
+ Last Name Attribute  = lastName
+ E-mail Attribute     = mail
+
+.. _enable_ldap:
+
+Enable LDAP : required
+    Whether to use LDAP for authenticating users.
+
+.. _ldap_host:
+
+Host : required
+    LDAP server hostname or IP address.
+
+.. _Port:
+
+Port : required
+    389 for un-encrypted LDAP, 636 for SSL-encrypted LDAP.
+
+.. _ldap_account:
 
- Enable ldap  = checked                 #controls if ldap access is enabled
- Host         = host.domain.org         #actual ldap server to connect
- Port         = 389 or 689 for ldaps    #ldap server ports
- Enable LDAPS = unchecked               #enable disable ldaps
- Account      = <account>               #access for ldap server(if required)
- Password     = <password>              #password for ldap server(if required)
- Base DN      = uid=%(user)s,CN=users,DC=host,DC=domain,DC=org
+Account : optional
+    Only required if the LDAP server does not allow anonymous browsing of
+    records.  This should be a special account for record browsing.  This
+    will require `LDAP Password`_ below.
+
+.. _LDAP Password:
+
+Password : optional
+    Only required if the LDAP server does not allow anonymous browsing of
+    records.
+
+.. _Enable LDAPS:
+
+Enable LDAPS : optional
+    Check this if SSL encryption is necessary for communication with the
+    LDAP server - it will likely require `Port`_ to be set to a different
+    value (standard LDAPS port is 636).  When LDAPS is enabled then
+    `Certificate Checks`_ is required.
+
+.. _Certificate Checks:
  
+Certificate Checks : optional
+    How SSL certificates verification is handled - this is only useful when
+    `Enable LDAPS`_ is enabled.  Only DEMAND or HARD offer full SSL security while
+    the other options are susceptible to man-in-the-middle attacks.  SSL
+    certificates can be installed to /etc/openldap/cacerts so that the
+    DEMAND or HARD options can be used with self-signed certificates or
+    certificates that do not have traceable certificates of authority.
 
-`Account` and `Password` are optional, and used for two-phase ldap 
-authentication so those are credentials to access Your ldap, if it doesn't 
-support anonymous search/user lookups. 
+    NEVER
+        A serve certificate will never be requested or checked.
+
+    ALLOW
+        A server certificate is requested.  Failure to provide a
+        certificate or providing a bad certificate will not terminate the
+        session.
+
+    TRY
+        A server certificate is requested.  Failure to provide a
+        certificate does not halt the session; providing a bad certificate
+        halts the session.
+
+    DEMAND
+        A server certificate is requested and must be provided and
+        authenticated for the session to proceed.
 
-Base DN must have %(user)s template inside, it's a placer where Your uid used
-to login would go, it allows admins to specify not standard schema for uid 
-variable
+    HARD
+        The same as DEMAND.
+
+.. _Base DN:
+
+Base DN : required
+    The Distinguished Name (DN) where searches for users will be performed.
+    Searches can be controlled by `LDAP Filter`_ and `LDAP Search Scope`_.
+
+.. _LDAP Filter:
+
+LDAP Filter : optional
+    A LDAP filter defined by RFC 2254.  This is more useful when `LDAP
+    Search Scope`_ is set to SUBTREE.  The filter is useful for limiting
+    which LDAP objects are identified as representing Users for
+    authentication.  The filter is augmented by `Login Attribute`_ below.
+    This can commonly be left blank.
+
+.. _LDAP Search Scope:
+
+LDAP Search Scope : required
+    This limits how far LDAP will search for a matching object.
+
+    BASE
+        Only allows searching of `Base DN`_ and is usually not what you
+        want.
+
+    ONELEVEL
+        Searches all entries under `Base DN`_, but not Base DN itself.
+
+    SUBTREE
+        Searches all entries below `Base DN`_, but not Base DN itself.
+        When using SUBTREE `LDAP Filter`_ is useful to limit object
+        location.
+
+.. _Login Attribute:
 
-If all data are entered correctly, and `python-ldap` is properly installed
-Users should be granted to access RhodeCode wit ldap accounts. When 
-logging at the first time an special ldap account is created inside RhodeCode, 
-so You can control over permissions even on ldap users. If such user exists 
-already in RhodeCode database ldap user with the same username would be not 
-able to access RhodeCode.
+Login Attribute : required        
+    The LDAP record attribute that will be matched as the USERNAME or
+    ACCOUNT used to connect to RhodeCode.  This will be added to `LDAP
+    Filter`_ for locating the User object.  If `LDAP Filter`_ is specified as
+    "LDAPFILTER", `Login Attribute`_ is specified as "uid" and the user has
+    connected as "jsmith" then the `LDAP Filter`_ will be augmented as below
+    ::
+
+        (&(LDAPFILTER)(uid=jsmith))
+
+.. _ldap_attr_firstname:
+
+First Name Attribute : required
+    The LDAP record attribute which represents the user's first name.
+
+.. _ldap_attr_lastname:
+
+Last Name Attribute : required
+    The LDAP record attribute which represents the user's last name.
+
+.. _ldap_attr_email:
+
+Email Attribute : required
+    The LDAP record attribute which represents the user's email address.
 
-If You have problems with ldap access and believe You entered correct 
-information check out the RhodeCode logs,any error messages sent from 
-ldap will be saved there.
+If all data are entered correctly, and python-ldap_ is properly installed
+users should be granted access to RhodeCode with ldap accounts.  At this
+time user information is copied from LDAP into the RhodeCode user database.
+This means that updates of an LDAP user object may not be reflected as a
+user update in RhodeCode.
+
+If You have problems with LDAP access and believe You entered correct
+information check out the RhodeCode logs, any error messages sent from LDAP
+will be saved there.
+
+Active Directory
+''''''''''''''''
 
+RhodeCode can use Microsoft Active Directory for user authentication.  This
+is done through an LDAP or LDAPS connection to Active Directory.  The
+following LDAP configuration settings are typical for using Active
+Directory ::
 
+ Base DN              = OU=SBSUsers,OU=Users,OU=MyBusiness,DC=v3sys,DC=local
+ Login Attribute      = sAMAccountName
+ First Name Attribute = givenName
+ Last Name Attribute  = sn
+ E-mail Attribute     = mail
+
+All other LDAP settings will likely be site-specific and should be
+appropriately configured.
 
 Setting Up Celery
 -----------------
 
 Since version 1.1 celery is configured by the rhodecode ini configuration files
 simply set use_celery=true in the ini file then add / change the configuration 
 variables inside the ini file.
 
 Remember that the ini files uses format with '.' not with '_' like celery
 so for example setting `BROKER_HOST` in celery means setting `broker.host` in
 the config file.
 
 In order to make start using celery run::
 
  paster celeryd <configfile.ini>
 
 
 
 .. note::
    Make sure You run this command from same virtualenv, and with the same user
    that rhodecode runs.
 
 
 Nginx virtual host example
 --------------------------
 
 Sample config for nginx using proxy::
 
  server {
     listen          80;
     server_name     hg.myserver.com;
     access_log      /var/log/nginx/rhodecode.access.log;
     error_log       /var/log/nginx/rhodecode.error.log;
     location / {
             root /var/www/rhodecode/rhodecode/public/;
             if (!-f $request_filename){
                 proxy_pass      http://127.0.0.1:5000;
             }
             #this is important if You want to use https !!!
             proxy_set_header X-Url-Scheme $scheme;
             include         /etc/nginx/proxy.conf;  
     }
  }  
   
 Here's the proxy.conf. It's tuned so it'll not timeout on long
 pushes and also on large pushes::
 
     proxy_redirect              off;
     proxy_set_header            Host $host;
     proxy_set_header            X-Host $http_host;
     proxy_set_header            X-Real-IP $remote_addr;
     proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header            Proxy-host $proxy_host;
     client_max_body_size        400m;
     client_body_buffer_size     128k;
     proxy_buffering             off;
     proxy_connect_timeout       3600;
     proxy_send_timeout          3600;
     proxy_read_timeout          3600;
     proxy_buffer_size           16k;
     proxy_buffers               4 16k;
     proxy_busy_buffers_size     64k;
     proxy_temp_file_write_size  64k;
  
 Also when using root path with nginx You might set the static files to false
 in production.ini file::
 
   [app:main]
     use = egg:rhodecode
     full_stack = true
     static_files = false
     lang=en
     cache_dir = %(here)s/data
 
 To not have the statics served by the application. And improve speed.
 
 
 Apache virtual host example
 ---------------------------
 
 Sample config for apache using proxy::
 
     <VirtualHost *:80>
             ServerName hg.myserver.com
             ServerAlias hg.myserver.com
     
             <Proxy *>
               Order allow,deny
               Allow from all
             </Proxy>
     
             #important !
             #Directive to properly generate url (clone url) for pylons
             ProxyPreserveHost On
     
             #rhodecode instance
             ProxyPass / http://127.0.0.1:5000/
             ProxyPassReverse / http://127.0.0.1:5000/
             
             #to enable https use line below
             #SetEnvIf X-Url-Scheme https HTTPS=1
             
     </VirtualHost>

 Troubleshooting
 ---------------
 
 - missing static files ?
 
  - make sure either to set the `static_files = true` in the .ini file or
    double check the root path for Your http setup. It should point to 
    for example:
    /home/my-virtual-python/lib/python2.6/site-packages/rhodecode/public
    
 - can't install celery/rabbitmq
 
  - don't worry RhodeCode works without them too. No extra setup required
 
 - long lasting push timeouts ?
 
  - make sure You set a longer timeouts in Your proxy/fcgi settings, timeouts
    are caused by https server and not RhodeCode
 
 - large pushes timeouts ?
  
  - make sure You set a proper max_body_size for the http server
