Description:
While max_user_connections is set to 0 only one session is available. It affects both local & remote connections.

How to repeat:
In the my.cnf the max_user_connections=0
Try opening 2 sessions withthe same user ID

Suggested fix:
1. Change the max_user_connections=(arbitrary number ie. > 0)
2. Fix the variable
