I looked on the server and I have two license keys. One is for 50 named users, the other is for 25 concurrent users. There is no expiration date in expires.
On the server I have 14 sessions logged in. So why am I getting this error? I looked at the users account and switcher her from concurrent to named but I still don't see why she could not log in.
Also I have to frequently restart the server TomCat 5.5 in order to cleanup sessions. They never seem to go away. But I get unable to login errors when the server has only 30 some users logged in.
