I am testing an upgrade from v1.16.3 to v1.17-rc3 so I can try configuring OAuth2.0 for email and ran into an interesting error.
Upon completing all the steps to perform the upgrade, I signed out of the admin panel. Upon attempting to sign in again, the Sign-In page was just stuck saying "Validating"
I had to modify my agent account from the ost_staff table to reset the password before I was able to sign-in again and I was immediately prompted to change my password. After doing so, I tried logging out and signing back in again. And it's stuck validating again.
Disabling the Password Policy Plugin fixes the issue.
Reenabling this plugin and trying to set different passwords after I have reset it to log in, some passwords it is stuck verifying and others give me an Access Denied error.
I tried lowering the complexity requirements and now I'm getting nonsense errors (see image) that will not allow me to set a new password
I have also tested a user account and it had no issues logging in.
I'm not entirely sure what is happening here, what else to test, or if this is even worth a forum post as this is still an RC.
