Recently one of my company employee resigned and leaved the company, so I added him in Deny Group in my Lotus Domino Server 8.5 Server. After few days he came back and rejoined, I removed him from the DENY ACCESS group, but still he was getting “You are not authorized to use the server” when trying to access his mail box using his notes client.
As showed in the image below . . .
I checked every setting on domino server for about 2 hours and finally found that NOTES caches the DENY ACCESS GROUP. I used the following command at SERVER CONSOLE of Domino Server to clear the cache and then the client was able to access his inbox 🙂
sh nlcache reset
