[Bioclusters] pointers on cluster integration with MS activedirectory environments

[Daniel.G.Roberts at sanofi-aventis.com]

Also Vintela VAS should work..
Anyone have first hand experience with using either centrify or vas in their cluster for user authentication?

I gather that you still have to run a lightweight ldap server on the headnode in order to have the compute nodes authenticate the user..
thoguths?
