How to integrate Active Directory users to an already configured VCS two node (non-secure) cluster

Hello colleagues,

I have the following situation:

An already configured two node VCS cluster (6.01 version) in Solaris 10 Sparc. We have installed the cluster in non-secure mode. The cluster has been working and the only configured used is the "admin" built in account.

We have a Active Directory environment and we want to integrate its users to the VCS cluster. Is it possible to do that? We have to reconfigure the cluster in secure mode to do that? If yes, how to reconfigure an already configured cluster?.

Thanks in advance and best regards
