SSO on linux

Hi,

Could some one gimme some inputs / references about any existing howtos or 
guides on implementing 'Single Sign On' on a linux server using Kerberos,  
which is connected to a Win2K KDC. 

Basically, I wish to enable seamless SSO on this heterogenous network 
consisting of both W2K as well as linux (FC1) servers, where some services 
would be provided by W2K machines, while others from linux machines. 

I had googled quite a bit and stumbled upon Microsoft Services For Unix (SFU) 
framework, but am a bit wary of it and think there should be some other way 
to implement this. 

Samba that ships with FC1 (samba-3.0.0-15) seems to be kerberised out of box 
and could be setup with a few entries like 'security = ADS' and so on...

I am looking for ways to kerberise Apache, VSFTPD, Postfix, MySQL and OpenLDAP 
to start with.

Any help is appreciated.
Regards.
