this is my first post to this list, I'll start off by saying I'm glad to
have found it, being that it looks more active than some other resources I
have found.

here's what I'm trying to do, I'm not sure if it will work the way that I
might want but here goes : I need to migrate users account from a redhat box
to a Solaris box ( I realize this should be the other way around...), but I
would like for them to be able to keep their passwords intact since I have
to migrate *alot* of users. Sooo, I'm hoping that I can copy the passwords
from the redhat box (MD5 encrypted I believe) to the Solaris box (which uses
DES I believe, I'm not too familiar with Solaris) and have the Solaris
machine be able to understand the md5 passwords as well as native solaris
ones.

>From what I've gathered I need to compile a pam module and insert into the
pam.conf authentication stack. I took a guess and tried to compile just the
pam_unix module, I had some trouble doing this :

# uname -a
SunOS 5.9 Generic sun4u sparc SUNW,Ultra-5_10
# cd Linux-PAM-0.77
# ./configure

... [ autoconf out ]

# mkdir security
# cp _pam_aconf.h ./security/ [ make it so we can find _pam_aconf.h, code
includes <security/_pam_aconf.h> ]
# cd ./modules/pam_unix/
# make
mkdir -p ./dynamic

*** Building pam-unix module of the framework...

i think it works, I have a pam_unix.so.....

I hope some of the above helps someone, but also would like to know if I'm
going about this the right way, any comments of suggestions would be
****greatly appreciated****.
