[K12OSN] yum update - user auth

[Daniel Kuecker]

Hello World!

I did a yum update on K12LTSP 5 and now I get random students not able
to log into the thin clients. I get the following error:

Mar  8 12:50:41 k8thin gdm[30782]: pam_unix(gdm:auth): check pass; user
unknown
Mar  8 12:50:41 k8thin gdm[30782]: pam_unix(gdm:auth): authentication
failure; logname= uid=0 euid=0 tty=192.168.10.1:1 ruser=
rhost=192.168.10.1

pam_sm_open_session
Mar  8 12:50:47 k8thin gdm[30782]: PAM unable to resolve symbol:
pam_sm_close_session

Users authenticate to windows AD using pam.
I have K12LTSP 6 server and the users can log on fine there. Any
suggestions?

Thanks
Daniel
