Description of problem:
After configuring the maxlogins parameter on /etc/security/limits.conf
I get an odd behavior when trying to login multiple times with
different user accounts.

The following line is inserted in /etc/security/limits.conf:

*    hard    maxlogins    2

After rebooting the system I am able to login with user1 (a regular
unprivileged user) at three terminals simultaneously. I then proceed
to login with user2 (another regular unprivileged user) at the fourth
terminal and to my surprise I get a message stating that user2 has
exceeded his maximum login count. The point is that user2 is not
logged on at all. The same happens with other users. I must then
logoff with user1 (at least from one terminal) to be able to login
with user2.


Version-Release number of selected component (if applicable):
pam-0.75-54

How reproducible:
Always

Steps to Reproduce:
1. Insert "*    hard    maxlogins   2" in /etc/security/limits.conf.
2. Reboot.
3. Login with the same unpriviliged user on three differente terminals.
4. Try to login with another unpriviliged user on yet another terminal.

    

Actual Results:  I am unable to login with the second unpriviliged
user and get a message stating such user has exceeded his maximum
login count.

Expected Results:  Login with the second user should be normal as it
is not logged on at all.
