Email address not allowed as username anymore since upgrade to 1.3
Posted: Wed Apr 29, 2026 4:49 am
Hello,
I've noticed that in NagiosXI 2026 1.3 it's not possible anymore to change the username to an email address anymore, which we always did for AD users.
Error:
Usernames can only contain letters, numbers, dots, underscores, and hyphens.
Must enter valid username, display name, and email for each user.
I can change the username afterwards but then I get a warning that this is not recommended
Kind regards,
Peter
