Yes.

If you want to postpone having to get your users to reset their
passwords, you could try the pam-passthru plugin:
http://cvs.fedoraproject.org/viewcvs/ldapserver/ldap/servers/plugins/pam_passthru/README?root=dirsec&rev=1.6&view=auto

I was hoping that I could take the Linux PAM MD5 and plonk it inside
Directory Server but this doesn't seem possible. Unless there is some
plugin designed for this that understands Linux MD5?

Not that I know of, but it shouldn't be that difficult to write using
the existing pwdstorage plugins as a starting point.
You might try the crypt format. On most linux platforms, system crypt uses MD5.
Thanks

Fedora Directory Users,

I have a bunch of users currently using local RHEL 4 local
unix user
accounts for their usernames and passwords and I would like
to migrate
them to Directory Server. My question concerns the MD5 sum password.

I tried adding a user joeltest with password joeltest and I
got hash:
JqBiQXU4$gnJeKmNzXy.kaXUaBIygs0

from RHEL but I got hash:

WGvQgGYUH2UOX2ZA1IQeyQ==
This value is the base64 encoded value of the md5 digest of the password, and is the same as the md5 digest of "joeltest": $ echo -n "joeltest" | openssl dgst -md5 -binary | openssl base64 WGvQgGYUH2UOX2ZA1IQeyQ== $

Regards.

>From Directory Server when I set the same password.

I'm guessing this is to do with further encodings placed on the password hash. Hoping someone has done this before and can
point me in
the right direction?

Thanks

Joel
