When you connect to an agent, you are authenticated through a login module. You acquire the native roles of that login to create a set of credentials for your session. You can add credentials to your session by providing another login ID and password. The additional login can be through the same login module or a different login module. After the additional login is authenticated, native roles for the new login are added to your session. This allows you to build up a set of credentials for session to perform the desired tasks.
Right click on a connected agent in the Agent Management Console in Sybase Central and select Add Credential, or select File | Add Credential.
Enter a new user ID and password to add additional login information.
Click OK.
If successful, your session assumes additional privileges of the new login credentials.
