Active Directory - Web Authentication

I initally posted this on the Domino 7 forum in error …Opps

I have set up Directory Assitance & an Ldap entry to our active directory… (connects successfully).

I want to allow user to authenticate to web applications using their AD credentials.

I have a people group in the ACL “*/CN=Users/DC=ourcompany/DC=net” … with author access.

but they still fail to authenticate …

am i missing something ??

i followed the lotusphere presentation to set it up…

Any pointers or help appreciated …

Thanks Rob
