Solution:

1.Check for the user if it is already exists in OID(since it is doing some kind of authentication while creating the user in OF)

2.This error normally happens if the user is already available i the LDAP cn=OracleContext.
cn=ACCOUNTS,cn=subscription_data,cn=subscriptions,orclApplicationCommonName=IDMIDM,cn=EBusiness,cn=Products,cn=OracleContext,dc=test,dc=com,dc=in.

3.So deleted the entries related to the user and recreated the user again.
