Hi Francisco, the problem is not actually in passwd itself but the problem is in the pam, which is called to modify user password. [particularly in pam_unix_passwd.c, I doubt the function pam_sm_chauthok()] I'm investigating this now. Reassigning to pam maintainer. |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Description of problem: If you change the attributes of the /etc/passwd, /etc/shadow, /etc/groups and /etc/gshadow this way: chattr +i /etc/group chattr +i /etc/gshadow chattr +i /etc/shadow chattr +i /etc/passwd and then, as user root you try to change the password of another user, then the message you get is: # passwd user Changing password for user optenet. New password: Retype new password: passwd: all authentication tokens updated successfully. But the password remains unchanged, since the files necessary to change it are not accesible. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.chattr +i /etc/group chattr +i /etc/gshadow chattr +i /etc/shadow chattr +i /etc/passwd 2.passwd user Changing password for user optenet. New password: Retype new password: passwd: all authentication tokens updated successfully. 3.Login as user with the new password fails. Expected Results: You should receive a message saying that the password cannot be changed due to the file attributes. Additional info:
