OIM User Creation : An Error occurred while performing create user operation. Unable to get LDAP connection

This post covers an issue that I encountered on Oracle Identity Manager (OIM) while creating new user in OIM. Error I received on screen was “Error occurred while performing create user operation. Unable to get LDAP connection, and the root cause is – null“.  OIM during installation or later can be integrated with LDAP server using LDAPSync . More on LDAP Sync herehere, and here

  • On user creation in OIM, LDAPSync should create this user in LDAP Server as well.



If you hit this problem then check error in OIM diagnostic logs at $DOMAIN_HOME/servers/[oim_server1]/logs

  • If you hit error like above then check  IT Resource (Manage IT Resource) in OIM Advanced Administration Console


  • Search for IT Resource Type Directory Server and change Connection Pooling Supported to False   (This issue seems to be fixed in OIM BP03)

I have a different failure for the user creation:

I made the change for the search base from dc=comp, dc=com to cn=users,dc=comp,dc=com

it still fails the same.

i have oim11.

@ Mike,

Search base dc=comp,dc=com is right you don’t have to change this.

Please share what values you entered during config.sh (durign OIM configuration) –

LDAP Server screen, provide the following details
k) Directory Server Type: ????
l) Directory Server ID: ???
m) Server URL: ldap://??????:???
n) Server User: cn=oimLDAP,cn=systemids,dc=?????
o) Server Password: *******
p) Server Search DN: dc=????
Click Next

On the LDAP Server continued screen, provide the following details
q) LDAP Role Container: cn=Groups,dc=????
r) LDAP User Container: cn=Users,dc=??????
s) User Reservation Container: cn=Reserve,dc=???
