Redhat Solutions for key based authentication

[Jimmy Stewpot]

Hello,

I am interested to know if Redhat have any solutions that would allow 
key based SSH authentication to be centrally managed. Currently using 
NIS+ and would now like to start managing the keys centrally. I have 
found a kerberos/GSSAPI patch to allow key authentication via kerberos 
however i am wondering if there are any Redhat supported platforms for 
that type of Technology?

Regards,

Jimmy
