Re: [Freeipa-users] FreeIPA 3.3 and Solaris 10 Client Integration:
Hi, I have earlier posted a guide on how to set up Solaris 11 and 11.1 as a client to IPA with NFS 4 with Kerberos and autofs on freeipa-users and the difference for Solaris 10 should be minor adjustments. I will add that guide to the Freeipa-wiki during this weekend and if you can not find the guide by searching through earlier posts i can post it again.
