Hi Atul,

Please let me know incase you tried integrating LDAP with Oracle Enterprise Manager 11g. This is to provision LDAP users to use OEM.

@ Jiby,
You need authentication & authorization to access OEM 11g.

OEM 11g provides three ways to authenticate users who needs access to OEM

a) Repository-Based Authentication
b) SSO-Based Authentication
c) Enterprise User Security Based Authentication

You can use option c) EUS based authentication which means you can use LDAP server (OID) for authentication.

For authorization use OEM Authorization Model.
