I have the same error:

Joomla 1.5.25
Ran all the tools to check the databases.
Get what looks to be a Javascript dialog box centered on a gray screen that says 'not authorized'
I'm logged in as a Super Admin
Other Super Admins report same issue, logged in to the admin side, trying to add a new user. The ajax email and user name checking say both are valid.
Tried it with and without the mootools upgrade plugin enabled, same results.
Nothing in the error log.
Any help would be appreciated.
