Good Day ,,I am failing to make any changes using netxms desktop client everything is giving me error: access denied but i am logged on with the only account thats there : admin . I cant even create a new user with the same error.
This is a fresh installation and server running on UBUNTU 22.04 using MySQL.
Check access rights for the user / group and make sure that "Edit server configuration variables" is enabled.
Since you are using "admin" user, it inherits access right from group "Admins" (in default configuration).
This permission is enabled by default, but maybe someone removed it for some reason.
