[Fedora-directory-users] Linux (RH and FC) & Solaris 8 / 10 group/netgroup and passwd Advice Desperately Needed [OT?]

[Vadim Pushkin]

Hello All;

My network, which once consisted of mostly Solaris 2.8 and Linux (Fedora Core and ReHat),
now consists of mostly Windows 2k3 servers and XP boxes, with a still a large amount of
Linux and Solaris Servers, is becoming a nightmare to administer and I am desperately
seeking some advice.

I would like to simplify all account information on my Solaris 2.8, Solaris 10 and Linux
servers/workstations to lookup and authenticate user account info, as well as what is now
in NIS netgroup and group, against one of my many AD servers. 

Would FCS help me at all?  Or would it further complicate my already complicated
environment?

Could someone point me in the right direction for how to get my *nix boxes to perform what
I am looking for them to do?

I've found a few articles for Solaris 10, but very little information for Solaris 8. 
Also, not sure if I need some additional PAM modules and or entries, especially for
Solaris 8 which I am clueless for.

While I realize that this question might be off-topic, I have nowhere else to look, I
therefore apologize in advance if this posting has offended anyone.

Thank you,
