Thanx Jurij,

I'll check it out first thing tomorrow. I have been with oracle, discussing this issue for the last three days and they so far had only been giving me a wishy washy asnwer. My question was when the DB does a remote user authentication, how would oracle come to know of the os_user name. Does it get from the client environment or through the UID parameter. Looks like they weren't ready to answer this qustion. But for me it is necessary, if I want to authenticate the web users' scripts, through the web client.

I'll as a first thing tomorrow would go through it. Thanx for pointing in the right direction.

Thanx,
Sam
