Documentum : DA : LDAP Servers Configuration, dm_LDAPSynchronization job

February 28, 2017February 28, 2017 | Huseyin OZVERENHuseyin OZVEREN | 0 Comment | 1:44 AM

Hello,

I would like to present in this post, the LDAP servers configuration in Documentum Administrator (DA) and the dm_LDAPSynchronization job.

Creation of LDAP server configuration:

  1. Go to the LDAP Servers node in DA:
  2. Click on the FILE > LDAP Server Configuration menu:

  3. Fill in the informations concerning the LDAP server:
    Warning: the name of LDAP Server Configuration must be identical to domain name.

    In update mode, the password is necessary in order to modify others informations:
  4. Go on to the Sync & Authentication tab:

  5. Go on to the Mapping tab:
  6. Go on to the Failover tab:

LDAP Synchronisation job : dm_LDAPSynchronization:

  1. Go to the Jobs node in DA:
  2. Go on to the Job Properties:
  3. Go on to the Schedule tab:
  4. Go on to the Method tab:
  5. Go on to the SysObject Info tab:

The job dm_LDAPSynchronization creates item of « dm_job_request » type for the jobs :
+ dm_UserRename : « object_name=’UserRename’, job_name=’dm_UserRename’ » to rename users
+ dm_GroupRename : « object_name=’GroupRename’, job_name=’dm_GroupRename’ » to rename groups

DQL: List LDAP being used to authenticate users

  • Source of Users 
    select distinct user_source from dm_user;

  • OS Users 
    select user_login_name, user_login_domain from dm_user where user_source = ' ';
------------------------------------------

    select user_login_name, user_login_domain from dm_user where user_source = 'inline password';
