I'm currently going through the settings on a Laserfiche Rio installation that is mostly untouched since it was installed, but it was initially a LF 8 (I think) installation that sat unused for years, and was then upgraded to 10.1, so some things may be setup in strange ways.
Looking in the Laserfiche Admin console, under Repository Users, there are what I assume are standard accounts for Forms, Workflow, an Admin account. There's also an account called Test. Test is also the only account listed under "Repository Named Users".
Looking in the Forms user authentication configuration, it is connecting to the Laserfiche repository with the Test account, which seemed like it should probably be the Forms account instead. But the Forms account is "not a read/write named user." Trying to set the "Repository Named User" property to "Full" for the Forms account in the Laserfiche admin console gives the error "The number of registered repository named users has reached its licensed limit. [9352]"
