SPNEGO error on IE 8

21 Views

Hello Expert,

I'm configuration SPNEGO in SAP Netweaver 7.02 SP06 on Windows 2003 R2 Active Directory 64 Bit.

I followed the guides and documentation of troubleshooting but I am presenting the following problem

When trying to enter the Portal from Windows clients with browser IE 8, I can not login automatically,

I have reviewed the notes 968,191 - SPNego: Central Note

diagtool tool gives me the following error

LOGIN.FAILED
