Problem summary
**************************************************************** * USERS AFFECTED: All users of the z/OS Distributed File * * Service SMB Server. * **************************************************************** * PROBLEM DESCRIPTION: When attempting to setup multiple * * user sessions from a single windows * * server, only one session is allowed * * access at any one time . * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** Authentication for multiple user sessions issued from a Windows Server using encrypted password support will only allow one authenticated session at a time. When additional user session authentication requests are generated, the current authenticated session will be torn down allowing for the new session session to authenticate.
Problem conclusion
A code path in the encrypted password support was restricting the use of multiple user authentications sessions. Additional code was added to allowing the sessions to authenticate.
