sudo hanging for 10 minutes on Solaris 10

Hi,

My sudo ("sudo su - <user>") hangs for around 10 minutes before giving me the login prompt of the <user>.

I'm using the following Centrify versions on Solaris 10.

I do have "nscd" running on this server and I tried restarting "nscd" and Centrify DC and DA services but it's nothing better.

Anyone else having a similar problem?

CentrifyDC 5.1.0-497

CentrifyDA 3.0.0-428

Thanks for your help in advance!
