.TH gosa.conf 5 "2008-04-07" "GOsa v2.6" "Debian"
.SH NAME
gosa.conf - GOsa configuration file
.SH DESCRIPTION
The gosa.conf file contains configuration information for
.IR GOsa,
a powerful GPL'ed framework for managing accounts and systems in
LDAP databases.
.PP
The gosa.conf file is a XML style configuration file. It is parsed by
the GOsa web application during log in.  The file may contain
extra tabs and newlines for formatting purposes.  Tag keywords in the
file are case-insensitive. Comments should be placed outside of XML
tags and should be encapsulated inside of <!-- --> tags.
.PP
The gosa.conf file can be used to configure the look and feel, behaviour
and access control of the GOsa webinterface.
.SH Configuration layout

The configuration has to be specified inside of the <conf> tags. It
basically consists of three main parts: menu definition, definition
of subdialogs (tabbed dialogs) and the main configuration - including
information about several locations.

.B Layout example:

.nf
  <?xml version="1.0"?>
  
  <conf configVersion="...." >
    <!-- Menu definition -->
    <menu>
    ...
    </menu>
  
    <!-- Tabbed dialog definitions -->
    ...
  
    <!-- Global setup -->
    <main>
  
       <!-- Location specific setups -->
       <location name="">
         ...
       </location>
  
    </main>
  
  </conf>
.fi

.SH Menu definition

This tag defines the side and icon menu inside the
interface. Defining an entry here is no guarantie to get it shown,
though. Only entries with matching ACL's get shown.

There are two types of entries inside of the menu: section and plugin

.B Defining a section

Open a 
.I <section>
tag including a 
.I name
attribute. This will show up in the menu as a new section later on.
Own entries are not handled via I18N by default. Close the 
.I </section>
tag after your plugin definitions.

.B Defining a plugin

Open a 
.I <plugin>
tag including a 
.I "class"
attribute. The 
.I "class" 
should be present inside your GOsa setup - the entry will be ignored if it is not.

Plugins should have an 
.I "acl"
entry, that allows GOsa to decide wether a user is allowed to see a plugin or not.
The 
.I "acl"
string matches with an ACL definition done inside of GOsa.

You can override an icon by specifying the 
.I "icon"
attribute.

For every plugin, you can provide at least four additional hooks: 
.I postcreate,
.I postdelete,
.I postmodify
and
.I check.
These can be used to perform special actions when a plugins gets
a create, delete, modify or check request. As a parameter, these
keywords get a shell script or program to the task.

.I The
.B create / delete / modify
.I keywords

These keywords take a full executable path of a script. You can
provide certain parameters in form of LDAP attributes. '%uid'
will pass the current user id, '%dn' the current object dn, etc.

The script gets executed after create, delete or modify tasks.

.I The
.B check
.I keyword

This keyword takes a full executable path of a script. Check is
triggered after you press the
-I "Apply"
or
-I "OK"
button. The complete LDAP entry as it will be written to the
LDAP is passed to your script. If parts of the entry do not
match some logic of your script, just print an error message
to STDOUT. GOsa will show this message and abort the current
process of saving the entry to the LDAP.

.B Example menu definition:

.nf
  <menu>
    <section name="My account">
      <plugin acl="users/user:self" class="user" check="/usr/local/bin/test_user.sh" />
      <plugin acl="users/samba:self" class="sambaAccount" postcreate="/usr/local/bin/create_share '%uid'" />
    </section>
  </menu>
.fi

.SH Tabbed dialog definitions

Tab definitions define the sub plugins which get included for certain
tabbed dialogs. If you change something here, never (!) remove the
primary (the first) "tab" tag which is defined. Most tabbed dialogs
need a primary plugin.

.I "*tab"
should be looked for by a defined plugin. This one will take
every 
.I "tab"
defined
.I "class"
and will show it inside of a tabbed dialog
with the header defined in
.I "name".

.B Example tabbed dialog definition:

.nf
  <grouptabs>
    <tab class="group" name="Generic" />
    <tab class="environment" name="Environment" />
    <tab class="appgroup" name="Applications" />
    <tab class="mailgroup" name="Mail" />
  </grouptabs>
.fi

.SH Main section

The main section defines global settings, which might be overridden by
each location definition inside of this global definition.

.B Example layout:

.nf
  <main default="Example Net"
        list_summary="false"
        ... >

        <location name="Example Net"
                  hash="md5"
                  dnmode="cn"
                  ...

                  <referral url="ldaps://ldap.example.net:636/dc=example,dc=net"
                            admin="cn=gosa-admin,dc=example,dc=net"
                            password="secret" />

        </location>

  </main>

for more information.
.PP

.B session_lifetime
.I int
.PP
The
.I session_lifetime
value defines when a session will expire in seconds. For Debian systems, this will

the value inside of your php.ini instead.
.PP

.B noprimarygroup
.I bool
.PP
The
.I noprimarygroup
variable enables or disables the group filter to show primary user groups. It is
time consuming to evaluate which groups are primary and which are not. So you may
want to set it to

.B ldap_filter_nesting_limit
.I integer
.PP
The
.I ldap_filter_nesting_limit
statement can be used to speed up group handling for groups with several hundreds of members.
The default behaviour is, that GOsa will resolv the memberUid values in a group to real names.
To achieve this, it writes a single filter to minimize searches. Some LDAP servers (namely
Sun DS) simply crash when the filter gets too big. You can set a member limit, where GOsa will
stop to do these lookups.
.PP

.B sizelimit

.PP
.PP


.B Account creation options
.PP
.B uidbase
.I integer
.PP
The
.I uidbase
statement defines where to start looking for a new free user id. This should be synced
with your
.I adduser.conf
to avoid overlapping uidNumber values between local and LDAP based lookups. The uidbase
can even be dynamic. Take a look at the
.I base_hook
definition below.
.PP

.B gidbase
.I integer
.PP
The
.I gidbase
statement defines where to start looking for a new free group id. This should be synced
with your
.I adduser.conf
to avoid overlapping gidNumber values between local and LDAP based lookups. The gidbase
can even be dynamic. Take a look at the
.I base_hook
definition below.
.PP

.B minid
.I integer
.PP
The
.I minid
statement defines the minimum assignable user or group id to avoid security leaks with
uid 0 accounts.
.PP

.B base_hook
.I path
.PP

and
.I sasl.
These values will be overridden when using templates.
.PP

.B idgen
.I string
.PP
The
.I idgen
statement describes an automatic way to generate new user ids. There are two basic
functions supported - which can be combined:

 a) using attributes

    You can specify LDAP attributes (currently only sn and givenName) in
    braces {} and add a percent sign befor it. Optionally you can strip it
    down to a number of characters, specified in []. I.e.

.nf
      idgen="{%sn}-{%givenName[2-4]}"
.fi

    will generate an ID using the full surename, adding a dash, and adding at
    least the first two characters of givenName. If this ID is used, it'll
    use up to four characters. If no automatic generation is possible, a
    input box is shown.

 b) using automatic id's

    I.e. specifying

.nf
      idgen="acct{id:3}"
.fi

    will generate a three digits id with the next free entry appended to
    "acct".

.nf
      idgen="ext{id#3}"
.fi

    will generate a three digits random number appended to "ext".
.PP

.if
.PP

.B sambaidmapping
.I bool

.fi
.PP


.B Debug options
.PP
.B displayerrors
.I bool
.PP
The
.I displayerrors
statement tells GOsa to show PHP errors in the upper part of the screen. This
should be disabled in productive deployments, because there might be some
important passwords arround.
.PP

.B ldapstats
.I bool
.PP
The
.I ldapstats
statement tells GOsa to track LDAP timing statistics to the syslog. This may
help to find indexing problems or bad search filters.
.PP

.B ignore_acl
.I dn
.PP
The
.I ignore_acl
value tells GOsa to ignore complete ACL sets for the given DN. Add your
DN here and you'll be able to restore accidently dropped ACLs.
.PP

.B debuglevel
.I integer
.PP
The
.I debuglevel
value tells GOsa to display certain information on each page load. Value
is an AND combination of the following byte values:

DEBUG_TRACE   = 1

DEBUG_LDAP    = 2

DEBUG_MYSQL   = 4

.PP


.SH LDAP resource definition

For every location you define inside your gosa.conf, you need at least
one entry of the type
.I referral.
These entries define the way how to connect to some directory service.

.B Example:

.nf
  <referral url="ldap://ldap.example.net/dc=example,dc=net"
            admin="cn=gosa-admin,dc=example,dc=net"
            password="secret" />
.fi

.I url
is a valid LDAP url extendet by the base this referral is responsible for.
.I admin
is the DN which has the permission to write LDAP entries. And
.I password
is the corresponding password for this DN.

You can define a set of referrals if you have several server to
connect to.
