Greetings,

I have a very interesting issue that I need to resolve and I am hoping that ISA 2004 can help.

I have a client that has deployed Sharepoint 2003 but does not like the NTLM challenge response and would like to have a form logon.

They are aware that ISA 2004 has the ability to publish an OWA form logon and they are wondering if this can be used to authenticate user for Sharepoint.

I have searched the internet for a way of deploying a form log on for sharepoint and the only article I could find was : http://www.theserverside.net/articles/showarticle.tss?id=ImplementingSSO

Unfortunately this doesnĘt seem to work.

If anyone has any ideas I would appreciate hearing them.

Thanks.

Hi SPS_Dev,
I've been tring that solution from the following website as well.

http://www.theserverside.net/articles/showarticle.tss?id=ImplementingSSO

I cannot launch the default SP main page after I installed the CustomAuth under the ISAPI Filter list. The default STSFLTR.DLL always have the highest priority and I can't modify the priority sequence.

Just wondering if you manage to find a solution or any new findings to share.

Thanks.

Regards,
Col

Hi Col,

I took the CustAuth source Code and recompiled it with High Priority so that I could assign it a higher priority than the SPS ISAPI filter. Unfortunately this only resulted in sharepoint no longer responding. What happened is the CustAuth filter would authenticate the form request and then redirect the user to the SPS ISAPI filter at this point the Sharepoint ISAPI filter would not accept the credentials from the CustAuth filter and would request authentication to which the CustAuth ISAPI filter would respond by posting the cached credentials. Obviously this resulted in an infinite loop of authentication requests.

My final solution was to use the ISA OWA form login which is pointed to a Sharepoint Server.

Regards,
SPS_DEV
