ORA-20001: Unabled to call fnd_ldap_wrapper.create_user

Hi,
Recently we integrated our R12 instance with SSO/OID and we used provisiontype 4, which means no bidirectional flow of users. Subsequently when we tried to create users in R12 (not OID) we encountered the following error:
ORA-20001: APP-FND-02600: Unable to create user ALISBT due to the following reason(s):
ORA-20001: Unabled to call fnd_ldap_wrapper.create_user due to the followingreason:An unexpected error occurred. Please contact your System Administrator...

Fix:

When you have provision type 4 setup in your environment, you should set the following profile option correctly:

Application SSO LDAP Synchronization ==> DISABLED

In our environment it was set to enabled by default, due to which we faced the issue. Set the aforesaid provide option to disabled at site level and you will be able to create users successfully.

PS: We were able to overcome this issue quickly with help of my colleague and friend Srinivasan K, who is an expert in R12 SSO integration and I must acknowledge his excellent contribution here. Thanks Srini!
