Dear all,

I implement "Using Kerberos Authentication for Single Sign-On" with microsoft ADS.

I follow the online help

http://help.sap.com/saphelp_nw70ehp2/helpdata/en/43/4bd58c6c5e5f34e10000000a1553f6/frameset.htm

During configration, every thing looks ok.

But it still can't automatic logon ep when i use AD user.

The error message shows below:

LOGIN.FAILED
User: N/A
