NIS to Active Directory Migration

Hello,

This is my first ever post on Unix anything Smilie. I really am a total newb when it comes to Unix. I am fairly well versed in the Windows world though.
I have a project that I was pulled into which consists on migrating our Unix servers from authenticating with NIS, over to authenticating with Active Directory (company audit policy). All of the users already have user IDs in active directory for separate Windows accounts. There are over a 1000 users that we will have to migrate.
The main issue is that there are a lot of folder/files on these servers that are access controlled by NIS and when we migrate, we would need these controlled by AD (I believe). I'm sure that there are a ton of groups and files that would need this migration applied to them. What is the best way to go about this?
Some one threw out the option to use UNAB to help us out. What do you think about this tool? Is there others that would do a better job? Is there better ways to go about the whole thing? Any help would be appreciated. Thanks

It should not be that big a deal. You can see all users using niscat passwd and all groups using niscat group, as I recall, and form them into ldap user and group adds. You can process the niscat into command lines in a script using awk or sed or the glabal find and replace of any text editor or word processor. I would be surprised if there were not tools to automate this process, but it should not be a big deal. Probably wise to do groups before the users that depend on them. Then you can remove the nic from the system configuration and the ldap should perform the same function. Make a test ldap-only user and group to ensure ldap is working, and leave a test nis-only user and group to test that nis is turned off. Welcome to UNIX, a stream of text world within a gui world.
