Question

Can ISA Server authenticate for a child domain?

Asked by: caw01

Hello,

I have a website (wss 3.0) in a child domain.  (wss.domain.local)

I have users and an ISA server in the primary domain (domain.local).

I need users in wss.domain.local to be able to authenticate when they access our ISA server in domain.local.

Thanks for the help.

Authenticate as in give access in a rule based on group membership or what is that you want do to?
Since a child domain will automatically be trusted there is no reason why ISA could not authenticate those users.

Hi,

Yes it can me done by 3 methods.
1. Use LDAP Authentication on the listener and crate LDAP Server set for both domain and use Login expression to differentiate.
2. Use RADIUS Server set for authentication.
3. Make ISA Server part of the domain and it should be abl to authenticate users from both domains.

Thanks
Kumar

The ISA server is a member of the parent domain.  So your belief is that it should already be authenticating users?

 

by: Kumar_Jayant123Posted on 2009-09-15 at 08:43:46ID: 25336145

Yes if it is a part of the domain it should be able to do it already.. Why dont you test and see..

Do this test then.

Create a user set in the ISA Server and try to add a user from the child domain. see if it gives you any error messages.

The best and secure way will be using LDAP server for authentication. Crete Two LDAP Server set one for the Parent domain and one for chile domain. Use Login Expression to differentiate the LDAP Server set and it should work just fine.

Sorry...  It is indeed working.  I had to put @domain on the end of the username which I do not currently have to do for my primary domain users.

Is there any way to eliminate that on the child domain?

 

by: Kumar_Jayant123Posted on 2009-09-15 at 09:25:13ID: 25336616

I dont think so.. In domain the user credentils are forwarded to the DC and it does all the authentication.. The "@" or "domain\" is the only way to differentiate the user,
