Not sure exactly when it happened, which is unfortunate, but my Windows 2016 domain controller stopped accepting authentication from my calendar module. We use the calendar module right now for syncing on-call schedules and company holidays from an Exchange 2016 server.
The LDAP synchronization is working, using the same user/pass.
We’ve tried resetting the password, using a weak password, nothing seems to get it to authenticate. I can log in to owa using the credentials and get in just fine, browse the calendars just fine.
The computer attempted to validate the credentials for an account.
Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
Logon Account: [username]
Source Workstation: pbx
Error Code: 0xC000006A
I should add that, to me, this just came out of the blue. We’ve been using the same password for a few months with success, until just recently.
In FreePBX, after submitting settings, I see a red bar at the top of the screen with “SOAP client returned status of 401.”
