Login fields are greyed out in 7.4 after upgrade with dl.store.impl specified in 7.4 upgrade tool

Issue

• After setting dl.store.impl= in portal-upgrade-ext.properties and using the upgrade tool to upgrade from 7.0 to 7.4, login fields are greyed out in 7.4.

Environment

• 7.4

Resolution

• Double check your upgrade configuration and process per 7.4 upgrade documentation. The presence of the dl.store.impl in portal-upgrade-ext.properties in this case resulted in the login fields being greyed out, interfering with login in 7.4.
