user login and logout
by yangyiin from LinuxQuestions.org on (#5A4Q9)
Hi,
i have redhat 7 server and users are authenticated by AD(active directory) kerberos.I use sssd in order to talk to kerberos to authenticate user.
An user has issue and the rest work well.The user test can login but after short time his session is removed.
