Documentation :

pykota.schema :

    This file can be used to modify an existing LDAP directory
    to add the necessary object classes and attributes for use 
    with PyKota.
    
    Include it in your LDAP server's configuration.
    For example, with OpenLDAP under Debian :
    
        $ cp pykota.schema /etc/ldap/schema
        (no need to do this if you install from PyKota's Debian package)

    NB: With OpenLDAP under Red Hat-based distros, where /etc/ldap is 
        referenced, substitute /etc/openldap. e.g. 

        $ cp pykota.schema /etc/openldap/schema
        
    Then edit /etc/ldap/slapd.conf and add a line to    
    include the PyKota schema. You should have something
    like :
    
        # Schema and objectClass definitions
        include         /etc/ldap/schema/core.schema
        include         /etc/ldap/schema/cosine.schema
        include         /etc/ldap/schema/nis.schema
        include         /etc/ldap/schema/inetorgperson.schema
        include         /etc/ldap/schema/pykota.schema
        
    While this is not mandatory, you may want to create    
    some indexes to speed things up a bit :
    
      You should already have these :
      
        index objectClass eq
        index cn pres,eq,sub
        index uid pres,eq,sub
        
      But we recommend that you add these :  
      
        index pykotaUserName pres,eq,sub
        index pykotaGroupName pres,eq,sub
        index pykotaPrinterName pres,eq,sub
        index pykotaBillingCode pres,eq,sub
        index pykotaLastJobIdent eq
        
    Now you must ensure that the DNs PyKota will use to bind to
    your OpenLDAP server don't have search queries size limits,
    which gives for example (OpenLDAP 2.1.x or above) :
    
        limits dn="cn=pykotaadmin,dc=example,dc=com" size.soft=-1 size.hard=soft
        limits dn="cn=pykotauser,dc=example,dc=com" size.soft=-1 size.hard=soft
    
    Where pykotaadmin and pykotauser are the usernames used to bind to your
    OpenLDAP server within PyKota, respectively in complete ReadWrite mode 
    (as set in pykotadmin.conf) and in ReadOnly mode (pykota.conf).
    
    NB : YOU have to define the ACLs necessary for user pykotaadmin to
    have unlimited Read+Write access to your LDAP tree, and for user
    pykotauser to have unlimited ReadOnly access to your LDAP tree.
    In the sentence above, "unlimited" means no limit with regard to
    the number of records returned by a search operation. Of course
    you may want to restrict the access to only some attributes, but
    this is up to you to decide. An example giving full write access
    to the pykotaadmin user is :
    
        access to dn.subtree="ou=PyKota,dc=example,dc=com" 
               by dn="cn=pykotaadmin,dc=example,dc=com" write   
               
        access to dn.subtree="ou=People,dc=example,dc=com" 
               by dn="cn=pykotaadmin,dc=example,dc=com" write   
               
        access to dn.subtree="ou=Groups,dc=example,dc=com" 
               by dn="cn=pykotaadmin,dc=example,dc=com" write   
               
    Please adapt this to your own needs and configuration.
    
    Now, stop the OpenLDAP server :    
    
        $ /etc/init.d/slapd stop
    
    Generate the index files :    
    
        $ slapindex
        
    And finally restart the OpenLDAP server :    
    
        $ /etc/init.d/slapd start

    NB: On Red Hat-based distros, use '/sbin/service ldap stop' and 
        '/sbin/service ldap start' instead.
    
pykota-sample.ldif :

    You can use this file to initialize an LDAP tree for PyKota, if
    you want.
    
    The structure used in this file is NOT mandatory !
    Provided you put correct parameters into /etc/pykota/pykota.conf,
    you can structure your LDAP directory the way you want.
    
To use an LDAP directory as the Quota Storage, just modify  
/etc/pykota/pykota.conf to make it contain lines similar to the LDAP
related ones in conf/pykota.conf.sample, but adapted to your
own configuration. Also de-activate the PostgreSQL-related lines.
