halts the session.

    DEMAND

        A server certificate is requested and must be provided and

        authenticated for the session to proceed.

    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:

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 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.

Authentication by container or reverse-proxy

--------------------------------------------

Starting with version 1.3, RhodeCode supports delegating the authentication

of users to its WSGI container, or to a reverse-proxy server through which all

clients access the application.

When these authentication methods are enabled in RhodeCode, it uses the

username that the container/proxy (Apache/Nginx/etc) authenticated and doesn't

perform the authentication itself. The authorization, however, is still done by

RhodeCode according to its settings.

When a user logs in for the first time using these authentication methods,

a matching user account is created in RhodeCode with default permissions. An

administrator can then modify it using RhodeCode's admin interface.

It's also possible for an administrator to create accounts and configure their

permissions before the user logs in for the first time.

Container-based authentication

''''''''''''''''''''''''''''''

In a container-based authentication setup, RhodeCode reads the user name from

the ``REMOTE_USER`` server variable provided by the WSGI container.

After setting up your container (see `Apache's WSGI config`_), you'd need

to configure it to require authentication on the location configured for

RhodeCode.

In order for RhodeCode to start using the provided username, you should set the

following in the [app:main] section of your .ini file::

    container_auth_enabled = true

Proxy pass-through authentication

'''''''''''''''''''''''''''''''''

In a proxy pass-through authentication setup, RhodeCode reads the user name

from the ``X-Forwarded-User`` request header, which should be configured to be

sent by the reverse-proxy server.

After setting up your proxy solution (see `Apache virtual host reverse proxy example`_,

`Apache as subdirectory`_ or `Nginx virtual host example`_), you'd need to

configure the authentication and add the username in a request header named

``X-Forwarded-User``.

For example, the following config section for Apache sets a subdirectory in a

reverse-proxy setup with basic auth::

    <Location /<someprefix> >

      ProxyPass http://127.0.0.1:5000/<someprefix>

      ProxyPassReverse http://127.0.0.1:5000/<someprefix>

      SetEnvIf X-Url-Scheme https HTTPS=1

      AuthType Basic

      AuthName "RhodeCode authentication"

      AuthUserFile /home/web/rhodecode/.htpasswd

      require valid-user

      RequestHeader unset X-Forwarded-User

      RewriteEngine On

      RewriteCond %{LA-U:REMOTE_USER} (.+)

      RewriteRule .* - [E=RU:%1]

      RequestHeader set X-Forwarded-User %{RU}e

    </Location> 

In order for RhodeCode to start using the forwarded username, you should set

the following in the [app:main] section of your .ini file::

    proxypass_auth_enabled = true

.. note::

   If you enable proxy pass-through authentication, make sure your server is

   only accessible through the proxy. Otherwise, any client would be able to

   forge the authentication header and could effectively become authenticated

   using any account of their liking.

Integration with Issue trackers

-------------------------------

RhodeCode provides a simple integration with issue trackers. It's possible

to define a regular expression that will fetch issue id stored in commit

messages and replace that with an url to this issue. To enable this simply

uncomment following variables in the ini file::

    url_pat = (?:^#|\s#)(\w+)

    issue_server_link = https://myissueserver.com/{repo}/issue/{id}

    issue_prefix = #

`url_pat` is the regular expression that will fetch issues from commit messages.

Default regex will match issues in format of #<number> eg. #300.

Matched issues will be replace with the link specified as `issue_server_link` 

{id} will be replaced with issue id, and {repo} with repository name.

Since the # is striped `issue_prefix` is added as a prefix to url. 

`issue_prefix` can be something different than # if you pass 

ISSUE- as issue prefix this will generate an url in format::

  <a href="https://myissueserver.com/example_repo/issue/300">ISSUE-300</a>  

Hook management

---------------

Hooks can be managed in similar way to this used in .hgrc files.

To access hooks setting click `advanced setup` on Hooks section of Mercurial

Settings in Admin. 

There are 4 built in hooks that cannot be changed (only enable/disable by

checkboxes on previos section).

To add another custom hook simply fill in first section with 

<name>.<hook_type> and the second one with hook path. Example hooks

can be found at *rhodecode.lib.hooks*. 

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 use the 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 start using celery run::

 paster celeryd <configfile.ini>

.. note::

   Make sure you run this command from the same virtualenv, and with the same 

   user that rhodecode runs.

HTTPS support

-------------

There are two ways to enable https:

- Set HTTP_X_URL_SCHEME in your http server headers, than rhodecode will

  recognize this headers and make proper https redirections

- Alternatively, change the `force_https = true` flag in the ini configuration 

  to force using https, no headers are needed than to enable https

Nginx virtual host example

--------------------------

Sample config for nginx using proxy::

    upstream rc {

        server 127.0.0.1:5000;

        # add more instances for load balancing

        #server 127.0.0.1:5001;

        #server 127.0.0.1:5002;

    }

    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 / {

            try_files $uri @rhode;

       }

       location @rhode {

            proxy_pass      http://rc;

            include         /etc/nginx/proxy.conf;

       }

    }  

Here's the proxy.conf. It's tuned so it will not timeout on long

pushes or large pushes::

    proxy_redirect              off;

    proxy_set_header            Host $host;

    proxy_set_header            X-Url-Scheme $scheme;

    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       7200;

    proxy_send_timeout          7200;

    proxy_read_timeout          7200;

    proxy_buffers               8 32k;

Also, when using root path with nginx you might set the static files to false

in the production.ini file::

    [app:main]

      use = egg:rhodecode

      full_stack = true

      static_files = false

      lang=en

      cache_dir = %(here)s/data

In order to not have the statics served by the application. This improves speed.
