Making Lotus Notes Single Login work (if it’s broken on your machine)
I could kick myself if I were more limber … I spend 5 hours completely rebuilding my work machine today because I *thought* I had some security software gunking up the works. I was wrong, it was just Microsoft Windows being a PITA.
The problem:
Lotus Notes “Single Login” aka “Log in to Notes using your operating system login” aka “single sign-on” etc. is set but the password prompt always appears.
The clue:
You look in Control Panel -> Administrative Tools -> Event Viewer and you see an application error “Lotus Notes Single Logon” that reads; “Notes Single Logon will not function properly: No mapping between account names and security IDs was done.”
The solution:
Launch RegEdit and navigate key: “HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/NetworkProvider/Order” then edit the value (a string of comma delimited labels) and find the value “npnotes” and move this value in front of the “WebClient” value.
Please don’t ask me why this works. It just does … at least for me <sigh>
Helped – thankx!
Glad it helped. I struggled with it for a while and there was very little good information on the Lotus/IBM site. I figured, “if I couldn’t find the solution, there are probably others.” I’ll try to make this even higher on the Google search results.
Adding some keywords might help: Lotus Notes single sign on, SSO, etc.
