our users have to login to the Adaxes web service by using their username and password, no SSO is used.
I have configured the option in the web interface "domainless username".
It is working fine, till after some weeks/months the user cannot login anymore.
They get the error message" The account name is invalid. It is expected to be formatted either as 'DOMAIN\user' or 'user@domain'"
Login with the domain is still possible, without not.
I could fix it by deleting/re-adding the group of users to the web interface/access control, but after some weeks/months this happens again.
