Before anyone says you need to upgrade, yeah I know we are working towards that but due to complications with how the data structure is setup at the moment we cannot move them up to the latest versions. so with that out of the way.
ArcGIS enterprise portal 10.6 is not allowing any role that has a User, Viewer, or Publisher role to sign into their account. if I change them to Administrator then they can log in just fine, am I missing some setting that needs to be enabled to allow different Roles the ability's to sign into those accounts with those Roles? This seems like it would be simple but I haven't seen any documentation on anything similar to this issue.
