The LDAP integration module is somewhat ported to d6 via a patch.
There are some outstanding issues.
The user authentication and group to role matching appears to work. However, ldap users get an error on their first login and work fine on all log ins after that. I am offering $100 to anyone who can fix this error via a patch. This would result in ldap users who have never logged in before logging in without error and having their group-role mappings set.
The other most broken part of the module is the ldap data. If anyone is interested in another bounty for the release a fully working d6 port of the LDAP integration module with no errors and the three major components, auth, groups, data, working, please let me know.

PS:
Needs to work with drupal 6
This is fixed for you.
The only bug that remains is that the initial drupal role creation is only done on the second login. But that is an issue with ldap_groups and is no big deal as the roles need to be created only once anyway.
The ldap group mapping is done on the first login for every successive new user, which is what I believe you were after.
Drop me an email for the patched module.
