ey guys,

Ive been working SharePoint UPS with Claims authentication, but Ive a doubt. To get the connection working with adfs, should the SharePoint server be able to resolve the Domain name? In my case Ivexyz.com and abc.com. SharePoint is installed on Xyz.com and configured to allow users fromabc.com. The authentication is working, but when I try to create a UPS it says Ldap server unavailable. Any ideas?

ADFS is an authentication protocol *only*.

UPS needs a way to QUERY active directory... the LDAP protocol supports QUERIES.

so while your users may LOGIN / AUTHENTICATE with ADFS... the UPS will need a way to query AD using LDAP (and then there's also some mapping between the LDAP data and the ADFS claims).

The UPS will need to be able to locate (DNS/etc) the LDAP server, and communicate with it (ports)... while ADFS uses HTTPS (port 443), LDAP uses 389.
