pam_unix_cred: cannot load ttyname Error 0
Today i worked with Gianluca on some systems affected by authentication problem.
We obtained the following error:
Jun 17 13:48:02 system01 login: pam_unix_cred: cannot load ttyname Error 0
after connecting on local zone and putting username/password.
After analsys we found that recently someone has changed local hostname ( not zonename ) and /etc/hosts was not updated properly.
