Blowfish is the default encryption algorithm used by SUSE
since right around
9.2 or so, I don't remember for sure. Redhat uses MD5. You
will need to go
into Yast - Security and Users - Edit and Create Users, then
click on the
advanced options button. There you can change the default
cipher used to
MD5. Then change everybody's passwords. The new hashes
will be created
using MD5. Then you can copy into /etc/shadow on your
RedHat box and they
will work. i.e. As long as they are both using MD5. That's
the trouble
shooting part.
How Suse can use shadow passwords produced with the MD5
algorithm on RedHat
even while using blowfish? That a question for the Suse
forums.

Subject: [rhn-users] Passwords generated on SUSE don't work
on RedHat
Hello,
If I copy the encrypted password from
"/etc/shadow" on
the SUSE box and paste it to "/etc/shadow" on the
Red
Hat box, then I can't log into the Red Hat box.
However, if I copy an encrypted password from
"/etc/shadow" on the Red Hat box and paste it into
"/etc/shadow" on the SUSE box, I can log into the
SUSE
box just fine. I've noticed that encrypted password
on SUSE is twice as long as the encrypted password on
Red Hat.
This all has to do with a problem I'm tracking when
the NIS master is on SUSE and the NIS slave is on Red
Hat.
What is the difference in the way that SUSE encrypts
passwords versus the way Red Hat encrypts passwords
and why does a Red Hat encrypted password work on
SUSE, but a SUSE encrypted password doesn't on Red
Hat? Any idea on how I can begin to troubleshoot
this?
Thank you.
Rigoberto
