The Windows Login Integration is different than any of the Login Integrations being done with Linux and UNIX. When installing the PAMSC endpoint, you have the option within the installer's GUI to select 'PUPM Integration'. What that does is it lays down all of the configurations we typically had to modify for our Linux and UNIX Login Integrations. So, if we select that, we should be fine from here on out. There are no additional steps needed in order to have the Login Integration work on Windows.
Conflicting policies where one policy had Login Integration enabled and the other had Login Integration disabled. However, this is very tough to discover because there is nothing inside CA PAM that lets an administrator know if there are duplicate policies. They were using user groups and device groups, and obviously those groups are populated by their business needs. This was a user error on their end.
