Got everything set up, realms, profiles, policies, pulse connection set & components configurations - the correct profile is getting pushed down, and the authentication provider is installed to allow for an interactive windows logon. In the Juniper logs, I can see the machine coming in and it fails LDAP authentication for some reason and I get the above message.
Pulse connection is set to "Automatically at user login." and in the VPN Tunnel configuration I have Interactive Logon enabled.
PS. I can successfully authenticate and log in once at the desktop with no errors.
