The issue can be reproduced at will with the following steps:
1. Create a new user with the following username "12345" in Apps "Define User" form
2. In OID there is a corresponding entry
UID is 12345
UID is 98765
So at this stage, although the username has been changed and will work correctly, the original internal reference is still being used within OID
4. If you now have a situation where you need to create a separate new user "12345" in Apps, this should work without an error, but instead in Define->User form the following error appears:
"Unable to call fnd_ldap_wrapper_user due to the following reason: ORA-20001:
Unable to call fnd_ldap_wrapper_user due to the following reason:
A user with the given username already exists.
Please use a different username. (USER_NAME=12345). (USER_NAME=12345)"
The issue has the following business impact:
Due to this issue, specific new users cannot be created without knowing the previous history of user creation.
