I'm using OPNsense OPNsense 21.7.3_3-amd64 with authentication via LDAP + TOPTP for 2fa and I'm facing a problem with user authentication.
Every time I try to test a login in AD I get the following error:
error: 80090308: LdapErr: DSID-0C090436, comment: AcceptSecurityContext error, date 52e, v23f0
I used some logins for testing in the tab "System > Access > Tester" with TOPTP but without success, even the password being correct I get the above error.
The curious thing is, if I go to the LDAP user import tab I can list all normally, the error only occurs for users to login with the backend via AD.
Apparently it seems to be some systemic error, but I couldn't find anything on the internet other than that this error refers to an invalid username and password, even though the logins are valid.
Someone could tell me if you have a more verbose login mode or have you experienced this problem by chance?
