Title:
  Too many logins - sessions not cleared

Status in “openssh” package in Ubuntu:
  New

Bug description:
  Ubuntu 11.10 server example:

  When I configure user ice to allow only 3 logins logged out SSH
  sessions are not being cleared.

  /etc/security/limits.conf

  ice              hard    maxlogins       3

  The user ice can login and logout many times without problem but if
  they login 3 times and hit the maxlogins limit then logout of all
  sessions the user can't log back in again even though there are zero
  logged in sessions.

  /var/log/auth.log

  pam_unix(sshd:session): session opened for user ice by (uid=0)
  pam_limits(sshd:session): Too many logins (max 3) for ice

  PAM reports too many logins even though the user ice has no current
  logins.
