A few months ago, we increased our ArcGIS Enterprise security by changing the passwords to all of our ArcGIS Enterprise service accounts. One such account was the primary administrator. Things have been working great. It went without a hitch. However, since that day, we cannot use the new credentials to log in to ArcGIS Server Administrator Directory. We get an "Invalid credentials" error in red, below the salmon-colored form. However, the old password grants access. The Portal Administrator Directory, on the other hand, does accept the new password and not the old.
How can we fix this, so that the ArcGIS Server Administrator Directory only allows the new credentials for the primary administrator to allow access?
