I am setting up a new Domino server (new Org cert/new Domino Domain) but when I get to the final step, it errors out with the message "The only allowed characters in a domino domain are..." however, my Domino Domain is setup as BM_UAT?
I tried re-doing it by removing the underscore but still get the same message. Found out that error was actually referring to the Organization name and not the Domino Domain name. User was trying to include a / in the Org. to setup an OU which was not permitted.
Suggest to revise the error message to know that it is the Org that was incorrect and not the Domain.
