DBA user single sign-on

Hi,
We have more than 300 databases. We want to create DBA users for all databases, and all DBA users are required to change password after 30days. To manage local user is very difficult. We think about using Single sign-on.

Has any body implemented the single sign-on for DBA user?. I'm looking for
1- The brief document to implement
2- And any extra cost license involve?

Thank you. Received on Tue Aug 03 2004 - 05:57:07 CDT
