We use HP M4345 MFP's here with the HP DSS software. All the users can log into the MFP except for one particular user. I haven't been able to find out why. We are leaning towards her active directory account might be goofed. However I hate to delete the account and recreate it as it will cause a lot of extra work.
Looking for any advice before we have to proceed down that road.
I've never worked with HP's Digital Sending Software before, but I'd suspect that the troubleshooting necessary would be similar to troubleshooting any LDAP-based authentication integration. (From what I'm reading it looks like it doesn't have any special "hooks" for Active Directory and treats it as an LDAP server...)
I'd throw a sniffer at the traffic between the MFP and the domain controller(s) that it's validating the logon against and see what looks different between the "problem" user and a known-working user. Seeing the traffic on the wire is always a good thing.
