Describe the bug
The passcore does change the password. It confirms that and I can use new password after that. So this is working, but at the same time it throws lots of error messages. The first error is 'Access is denied. (0x80070005 (E_ACCESSDENIED))', then it disappears and then gives an error about complex password policies.

• If I change 'UseAutomaticContext' to 'false' then it doesn't change password at all.
• Username and password for LDAP user are correct - that's been confirmed.
• LDAPS on the Active Directory server is working. Verified with LDP.EXE app and the LDAP service account used for passcore.
• LDAP account has Domain Admin rights ATM.
• Old and new passwords are certainly not used before and complex enough. I'm testing with passwords like 'F@st3r-ce7ngo-ro@tto'. See the password policies screenshots at the bottom.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'password.blahblah.com' site to change password
2. Enter [email protected], old password, new password, new password.
3. Click 'Change Password' and wait
4. See error

Expected behavior
No errors.

Screenshots

Desktop:

• OS: Windows Server 2019
• Browser Chrome
• Version 93.0.4577.82

Additional context

1. Couldn't make v4.2.4 working at all so had to downgrade to v4.2.3. At least with this version it does change passwords.
2. Couldn't make it working with using installation PowerShell script so had to use instructions to install it manually.
3. Had to add Application Pool twice. First time as in the instructions and then within the website . Without that it gives "Server is not ready" error. See screenshots below.

Is there any back about this problem ?

[eduder]

Having the same problem on 4.2.4, running on a Ubuntu 20.04 server talking to 2016 Server AD. Locks the user account out and spams 400 errors in the browser log. Looks like there were previous bugs filed for this but it's been closed.

@igenkin - not sure if this will help you but we resolved this on 4.2.0 by changing the flag "LdapChangePasswordWithDelAdd" to false.
