Thanks for the help. The error I got is similar to an error I got before.
The keys are defined as follows:
[error] => Array
[message] => Unexpected username '<uid>' came back from external auth provider. Expected: '<systemid>'
[status] => 500
[title] => Internal Error
[uri] => https://<host>/@api/deki/users/authenticate?dream.out.format=php&dream.in.host=<host>&dream.in.scheme=https&dream.in.origin=<IP>&authprovider=12
bindingpw: <password string>
bindingdn: uid=<Authorized UID>,ou=people,dc=alaska,dc=edu
hostname: <ldap url>
