I would contact your Solution Provider.

Also note, that you are on an unsupported version of Forms. Version 9 was end of support December 31, 2021.

Hi,  not sure if you are using Directory Server, or how your users are set up. It could be that it hasn't synced with the password changes yet. There may also be something in event viewer, about your login.

There is a backdoor to regain access to Forms if this happens. Open the forms configurator and go to the Repository Tab. There is a place to enter a username and password which is used to establish a connection to LFS, however when you do this it also auto configures that account with rights as a Forms Administrator.

So temporarily change this to any Laserfiche User account, such as the built in Admin account (you will need to temporarily assign a full license). Then login to Forms with that account to re-establish access.

Interestingly enough, the connection between Forms and LFS continues to be established without any problems if you remove the named license from the account. This means you could keep the connection established with a non-named service account and just give that account a license when you need to restore administrative access.
