Comment 5 for bug 227383

Here is some information from the auth.log
First attempt when opening the network settings:
May 7 01:30:09 myname sudo: PAM unable to dlopen(/lib/security/pam_smbpass.so)
May 7 01:30:09 myname sudo: PAM [error: /lib/security/pam_smbpass.so: cannot open shared object file: No such file or directory]
May 7 01:30:09 myname sudo: PAM adding faulty module: /lib/security/pam_smbpass.so
May 7 01:30:20 myname sudo: user : TTY=unknown ; PWD=/home/user ; USER=root ; COMMAND=/usr/bin/network-admin
May 7 01:30:20 myname sudo: pam_unix(sudo:session): session opened for user root by (uid=0)
May 7 01:30:20 myname sudo: pam_unix(sudo:session): session closed for user root

Second attempt in user and group settings, I can't work on group settings on my home user name, see screenshot no.3
Then marking root and unlock to work on group settings, then password and pressing authenticate, the messages are:
May 7 01:45:17 myname polkit-grant-helper-pam[5966]: PAM unable to dlopen(/lib/security/pam_smbpass.so)
May 7 01:45:17 myname polkit-grant-helper-pam[5966]: PAM [error: /lib/security/pam_smbpass.so: cannot open shared object file: No such file or directory]
May 7 01:45:17 myname polkit-grant-helper-pam[5966]: PAM adding faulty module: /lib/security/pam_smbpass.so
May 7 01:45:28 myname polkit-grant-helper[5963]: granted authorization for org.freedesktop.systemtoolsbackends.set to pid 5933 [uid=1000] [auth=user]

Third attempt to open group settings: success
Why, after typing the password I didn't press authenticate, I just pressed enter and every window from user and root is available to scroll and work with.

Network administration is still not. And I have no idea what therefore has to be changed.
