+Subject: [PATCH] Fix error on changing user password by admin
+
+Previous change I8438bedaf7cead452fc499e484d23690b48894d9
+attempted to address bug LP#1728031 by improving upon
+patch https://review.opendev.org/854005 but missed the
+line that allows the keystone client to properly
+authenticate a cloud admin user that IS NOT in the
+default domain.
+
+Without this 1-line fix, a cloud admin that is not
+in the default domain will face an "incorrect admin
+password" error in the UI (despite the admin password
+being correct) and an authentication error in the logs,
+regardless of the endpoint type used (adminURL,
+internalURL or publicURL).
+
+Closes-bug: #1728031
+Change-Id: I018e7d9cb84fd6ce8635c9054e15052ded7e9368
+(cherry picked from commit da8e959298575127434e6e15aae5d1f0638a6e22)
