The finalized working bit for Active Directory LDAP was:
# Working LDAP Auth
cas.authn.ldap[0].order=0
cas.authn.ldap[0].name=Active Directory
cas.authn.ldap[0].type=AD
cas.authn.ldap[0].ldapUrl=ldap://<DC FQDN>:389
cas.authn.ldap[0].validatePeriod=270
cas.authn.ldap[0].poolPassivator=NONE
cas.authn.ldap[0].searchFilter=sAMAccountName={user}
cas.authn.ldap[0].baseDn=OU=Staff,DC=...
cas.authn.ldap[0].subtreeSearch=true
cas.authn.ldap[0].type=AUTHENTICATED
cas.authn.ldap[0].bindDn=CN=casbind,CN=Users,DC=...
cas.authn.ldap[0].bindCredential=<password>
# Working LDAP Auth
:D
I even got Duo MFA working today. Thanks all!
