= Authentication modules for AccountManagerPlugin
{{{#!box note
This page documents AccountManagerPlugin 0.4 and later with Trac 0.11 and later. If you are using older versions, please upgrade.
}}}
== !HtDigestStore
'''Package''':: acct_mgr.htfile
Used to store passwords in the htdigest file format.
{{{#!box warn
This password method may not work with [TracModPython mod_python] due to a bug using Python’s md5 module under `mod_python`. It has been reported that `mod_python` has trouble returning good MD5 strings. It has been speculated that this is because many Apache mods are using the same md5 source (PHP and so forth), but this is not confirmed. If you experience problems try [TracFastCgi FastCGI], [wiki:TracModWSGI mod_wsgi], [TracStandalone tracd], or use md5crypt patch (#8386).
}}}
To use this component to manage your password file, you need to enable it as described above and add some additional configuration to [TracIni trac.ini]:
{{{#!ini
[components]
; be sure to enable the component
acct_mgr.htfile.HtDigestStore = enabled
[account-manager]
; configure the plugin to store passwords in the htdigest format:
password_store = HtDigestStore
; the file where user accounts are stored
; the webserver will need write permissions to this file
; and its parent folder
htdigest_file = /var/trac/trac.htdigest
; the name of the authentication “realm”
; it can be any text to identify your site or project
htdigest_realm = TracRealm
}}}
== !HtPasswdStore
'''Package''':: acct_mgr.htfile
Used to store passwords in the htpasswd file format.
{{{#!box warn
This password method may not work with [TracModPython mod_python] due to a bug using Python’s md5 module under mod_python. If you experience problems try [TracFastCgi FastCGI], [wiki:TracModWSGI mod_wsgi], [TracStandalone tracd], or use md5crypt patch (#8386).
}}}
To use this component to manage your password file you need to enable it as described above and add some additional configuration to [TracIni trac.ini]:
{{{#!ini
[components]
; be sure to enable the component
acct_mgr.htfile.HtPasswdStore = enabled
[account-manager]
; configure the plugin to store passwords in the htpasswd format:
password_store = HtPasswdStore
; optional hash type selection
htpasswd_hash_type =
; the file where user accounts are stored
; the webserver will need write permissions to this file
; and its parent folder
htpasswd_file = /var/trac/trac.htpasswd
}}}
== !HttpAuthStore
'''Package''':: acct_mgr.http
Used to delegate authentication to the web server. This allows access to be restricted based on LDAP, a password file, etc, or some combination of them.
Note: This password store does not support listing/adding/removing users or changing passwords.
{{{#!ini
[components]
; be sure to enable the component
acct_mgr.http.HttpAuthStore = enabled
[account-manager]
; configure the plugin to use a page that is secured with http authentication
authentication_url = /authFile
password_store = HttpAuthStore
}}}
This will generally be matched with an Apache config like:
{{{#!apache
# HTTP authentication configuration…
Require valid-user
}}}
The above example assumes that you are hosting a single Trac project. If hosting multiple Trac projects, you might use something like this in project1's trac.ini:
{{{#!ini
[account-manager]
; configure the plugin to use a page that is secured with http authentication
authentication_url = /project1/authFile
password_store = HttpAuthStore
}}}
This could then be matched with an Apache config like:
{{{#!apache
…HTTP authentication configuration…
Require valid-user
}}}
{{{#!box note
'''authFile''' does not need to exist; but the Apache configuration '''must''' match the ''authentication_url'' setting.
}}}
{{{#!box important
Be sure to test your configuration by attempting a login with a valid user, and both a valid and '''invalid''' password to ensure that your Apache `` or `` section is getting executed. If it is not, you will be able to log in with an invalid password.
}}}
Note: If you are having trouble getting !HttpAuthStore to work, enable DEBUG-level logging, and check for !HttpAuthStore messages in your project's Trac log file.
== !SessionStore
'''Package''':: acct_mgr.db
Stores password information in the trac database. This may give better behavior if you have large numbers of users and are finding errors due to write contention on the password file. You must enable one or other of the hash method components. !HtDigestHashMethod is the default.
{{{#!ini
[components]
; be sure to enable the component
acct_mgr.db.SessionStore = enabled
; choose one of the hash methods
acct_mgr.pwhash.htdigesthashmethod = enabled
acct_mgr.pwhash.htpasswdhashmethod = enabled
trac.web.auth.loginmodule = disabled ;this is important, otherwise login does not work. ref: http://www.gossamer-threads.com/lists/trac/users/41969
[account-manager]
password_store = SessionStore
; choose one of the hash methods with corresponding supplemental option
hash_method = HtDigestHashMethod
db_htdigest_realm = TracDbRealm
;hash_method = HtPasswdHashMethod
;db_htpasswd_hash_type = sha
}}}
For sample configuration settings see [wiki:CookBook/AccountManagerPluginConfiguration#SessionStore our cookbook] page
For historic background of this `IPasswordStore` implementation see the [http://www.mailinglistarchive.com/trac-users@googlegroups.com/msg03696.html mailing list].
== !SvnServePasswordStore
'''Package''':: acct_mgr.svnserve
Allows Trac to use SVN users (may be in addition to Trac users). SVN server configuration option should be "svnserve". For more information, read chapter 6 of [http://svnbook.red-bean.com/ SVN book].
{{{#!ini
[components]
; be sure to enable the component
acct_mgr.svnserve.* = enabled
acct_mgr.svnserve.svnservepasswordstore = enabled
; choose one of the hash methods
acct_mgr.pwhash.htdigesthashmethod = enabled
acct_mgr.pwhash.htpasswdhashmethod = enabled
[account-manager]
password_store = SvnServePasswordStore
password_file = /path/to/svn/repos/conf/passwd
; choose one of the hash methods
hash_method = HtDigestHashMethod
hash_method = HtPasswdHashMethod
}}}
`password_file` points to a file which defines users/passwords this way : `user = password`.
== LDAP
'''Package''':: acct_mgr.adauth
Allows authentication against most LDAP based directories including Active Directory. See DirectoryAuthPlugin for details.
Meanwhile please check the following options:
stand-alone
* AccountLdapPlugin
permission store extension to Trac
* LdapPlugin, utilizes Trac HTTP Auth, so it's a ACL, not the authentication itself
!AuthStore for AccountManagerPlugin packaged as separate plugin
* LdapAuthnzPlugin
* LdapAuthStorePlugin that spun off of #1147 - a 'wontfix'ed enhancement request for AccountManagerPlugin
* http://pypi.python.org/pypi/TracLDAPAuth/ and
* TracLdapAuthPlugin as an enhanced fork of it
suggested native !AuthStore for AccountManagerPlugin (see [wiki:AccountManagerPlugin/AuthStores currently supported ones here])
* #1600, a spin-off of LdapPlugin, that we may add some day (needed preparation done, see #1602)
