SUMMARY: MD5 hashes for passwd/shadow

The general consensus was that I'm out of luck. An appropriate PAM module
would do the job, but as far as I could tell from
http://www.us.kernel.org/pub/linux/libs/pam/index.html (as suggested by
Frank Cusack) external PAM modules are only supported in Solaris 2.6+ (I'm
using 2.5.1).

Anand Buddhdev confirmed that FreeBSD (and probably other free Unix flavors)
supports mixed DES/MD5 hashes. We tested the original AIX (supposedly MD5)
passwords and they worked on a Red Hat distribution of linux, together with
some old DES passwords in the same file. As I mentioned in the original
message, no luck under Solaris.

Dan Stromberg suggested that I would have to change all the passwords...
which is more or less what I ended up doing. Actually, we hacked the radius
and pop3 daemons to dump the plain text passwords for a week or so, and
we'll use the output to generate good old crypt passwords for our Sun.

Thanks to all of you for your replies.

Regards,
Daniel
