Full Discussion: unable to reset user password
Operating Systems Solaris unable to reset user password Post 302233166 by BOFH on Saturday 6th of September 2008 11:06:40 AM
Old 09-06-2008
Just as a little note. I've had a similar problem on an old Sun box before. The problem was a passwd lock file in /etc. I used truss to watch passwd and it kicked back at this lock file. It had been created by another admin changing a password and his session bailed out leaving the lock file in place. Once I cleared it it fixed the problem.

So you might open another window to the server and log in as root. In the first window, type in passwd. Then shift to the second window and do a ps -ef | grep passwd. Next type in truss -p <pid of passwd>. In the first window type in the new password twice. The second window should show you where the problem is happening.

It might be a lock file or some other problem but truss is a helpful tool.

pwconv

pwconv(1M)                                                System Administration Commands                                                pwconv(1M)

NAME

       pwconv - installs and updates /etc/shadow with information from /etc/passwd

SYNOPSIS

       pwconv

DESCRIPTION

       The pwconv command creates and updates /etc/shadow with information from /etc/passwd.

       pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is
       already in /etc/shadow and should not be modified.

       If the /etc/shadow file does not exist, this command will create /etc/shadow with  information  from  /etc/passwd.  The  command  populates
       /etc/shadow  with  the  user's  login  name,  password,  and  password  aging  information. If password aging information does not exist in
       /etc/passwd for a given user, none will be added to  /etc/shadow. However, the last changed information will always be updated.

       If the  /etc/shadow file does exist, the following tasks will be performed:

                Entries that are in the  /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file.

                Entries that are in the  /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow.

                Password attributes (for example, password and aging information)  that exist in an /etc/passwd entry will be moved to the  corre-
                sponding entry in  /etc/shadow.

       The pwconv command can only be used by the super-user.
