Logon error with local user SSPLogonUser false 1385

[kevyn]

When trying to test the local logon via configuration app, or when trying to login using the master app, I get the error:

[DEBUG] WindowsUserFunctions::authenticate(): SSPLogonUser() false 1385
[ERR] AcceptSecurityContext failed with 8009030C

The local user account is a standard user local, and I can logon fine with the account into Windows.

I have tried with the following formats, but they all error:

• username
• hostname\username
• .\username

The password has not expired, is set to never expire, and the account is not disabled (as I can logon to it fine in windows).

Any help appreciated. Windows 11 on a new PC, Veyon 4.9.1
