SSGD 4.40.907 and SLES10-SP1 64bit - Invalid credentials while logging in

Question

Hello everybody.
As a test, I installed SSGD 4.40.907 on a SLES10-SP1 64bit virtual operating system (it's operating using the XEN hypervisor, paravirtualized mode).
The installation went well (I had to copy old libraries - namely, libexpat.so.0.5.0 and libgdbm.so.2.0.0 - from a previous version of SLES + ldconfig) and I was able to get to the login prompt but as soon as I entered the "root" password I got "Invalid credentials".
I tried again (in my test environment, the root password is VERY simple) but no dice; I checked the root password by logging into the system using SSH and it worked fine.
I tried with different local accounts (eg, ttaserv and ttasys) but got the same message.
Please notice that, under the very same piece of HW but using a SLES10-SP1 *32bit* under XEN, everything works as expected so it seems a 64bit OS related issue.
Thanks,
Rob

Casper,
Can you please try the following.
On the protected server please try to remove the account and remove the DPM agent. Reboot, after that please manually reinstall the DPM agent on the protected server -
http://technet.microsoft.com/en-us/library/hh757789.aspx.  Run the setdpmserver command and after completing successfully check the account to ensure the following.
1) It is set for the password not to expire and user cannot change password
2) Is included in the following groups, DCOM Distributed Users, DPMRADCOMTrustedMachines, and DPMRADmTrustedMachines.
If that all checks out, please goto the DPM console and tried to attach from the DPM console first and then try the powershell command if the console errors out. 
Here are some other things to check as well:
Step 1) Ensure NTLM is working - UNC from DPM to PS and back
Step 2) Ensure DCOM is enabled on protected server - Type DCOMCNFG > Computers > My Computer, right click and select properties, go to Default Properties and ensure "Enable Distributed COM on this computer" is checked
Step 3) Ensure all firewalls have needed ports open -

Step 4) Ensure user account is set to never expire and user cannot change password
Step 5) Try attach from DPM console first then DPM powershell
If that still does not work please ensure you are on the latest DPM patch and try again. 
For DPM2012 SP1 that is DPM3.6(Note: you will need to have RU3 installed prior)
