When the error message "Error in ldap_search_ext_s function" is encountered while loading the schema for ADAM (Active Directory Application Mode) using the LDAP Configuration Utility (LCU), there are two possible causes to investigate:

  1. There is an error in the schema_base in the config.ini of the LCU, or
  2. The User selected is not an Authorized User in the ADAM's Administrator group.

Assess and correct each of these potential problems as described here:

  1. The config.ini file can be found in the directory where LCU is installed.  In that file, ensure that the CN={¦} portion of the schema_base entry (as highlighted below) reflects the ADAM instance being managed. Check in ADSI Edit for the instance's correct value.

     schema_base = CN=Aggregate,CN=Schema,CN=Configuration,CN={81F55243-1526-41F9-89F4-B4F21EB43DD1}

  2. On the Load Schema window (accessible from Tools> Load Schema on the LCU menu bar), select Authorized User and enter the DN of a user that is in the ADAM's Administrator group.  Check in the ADAM to verify that the attribute msDS-UserAccountDisabled=FALSE for that user, and ensure that the user's password is set.
