If you plan to use an LDAP server for authentication, ensure that you set up and configure a working LDAP server.
LDAP authentication is deprecated and will not be supported in future versions.
Orchestrator supports these directory service types.
Windows Server Active Directory
Multiple domains that have a two-way trust, but are not in the same tree, are not supported and do not work with Orchestrator. The only configuration supported for multi-domain Active Directory is domain tree. Forest and external trusts are not supported.
