Description kenneth_porter 2001-12-28 18:48:05 UTC 
Prior to upgrading to RH 7.2, my root password was longer than 8 
characters, and entering the whole thing was accepted by su. Following the 
upgrade (sh-utils-2.0.11-5), I can enter the long password with the passwd 
command, but I must only enter the first 8 characters to su. su rejects 
the longer password.

I believe there's a similar problem with the main desktop login, so this 
may be a PAM issue.
Comment 1 Bernhard Rosenkraenzer 2002-01-09 15:16:49 UTC 
Works for me...
Are you sure MD5 passwords are enabled? (MD5 passwords are on if the password hashes in /etc/shadow start with "$1$")
Comment 2 kenneth_porter 2002-01-09 20:01:35 UTC 
MD5 is not specified in /etc/pam.d/system-auth, and there are no "$1$" style
prefixes in /etc/shadow.
Comment 3 Bernhard Rosenkraenzer 2002-01-22 22:46:39 UTC 
long passwords don't work unless md5 passwords are enabled. Please use
"authconfig" to fix your configuration.
