Java Security

Dear friends,

Our product is running on the App Server(weblogic/websphere...) and we also use security provider(OpenLDAP) and kerberos to support SSO. Before, when a user tyies to login in the first time, the way we use to authenticate the user is:
1) Accept the username/password
2) Query the security provider(OpenLDAP) to get the principles.
3) verity if the username/password is corrent or not.

As we know, to query the principles, we need to provide a search user(both username and password) if we configured the access control of the ldap server:
I have configured my envirioment as follows
1) In the LDAP server, configured the Middle Tire user(The Operating System user running the App Server) to have the permission to query principles.
2) The server is configured to runing on SSO envirioment.

My question is could I get the username/password of the OS user running the App Server at runtime so that I can query the ldap server without explicitly providing the search user?

Thanks,
RR
