Unable to login as a root

Hello all,

I have a software that requires a user authentication to work on it (not necessarily a root user, it can be any user).

The software uses the /etc/passwd file for the authentication. Thus only those users who are present on the Linux System can use that software.

I cannot login as a user root into that software but being able to successfully login as a normal user. However from past three weeks, I was being able to login into that software as a user root. Also I can login as a user root into the Linux System.

The file /var/log/messages show the following log:

Oct 18 08:19:58 bcmgmt1 scacim-pgsql(pam_unix)[9363]: authentication failure; logname= uid=26 euid=26 tty= ruser= rhost= user=root

Any idea?

Without knowing what the "software" is, there is no way to tell. Clearly something has changed in the way the "software" validates the root user. Perhaps you are attempting to login to the software from a remote location for the first time? Perhaps the software has been updated?
