Commit Message:

Line 14: internal_id= the primary key of the user or group as stored in db
Line 15: provider_id = <directory_name>:<id_of_entity_in_directory>
Line 16: 
Line 17: directory_name = name of the directory
Line 18: entity_in_directory = id of principal or group
it should be one of the options, not both in any case.

Or:

 url_encode(id=<internal>)

Or:

 url_encode(provider_id=<directory>:<id_with_directory)

There should never be both, unless there is a reason... but I do  not see any.

File 
backend/manager/modules/restapi/types/src/main/java/org/ovirt/engine/api/restapi/utils/DirectoryEntryIdUtils.java:

Line 9: public class DirectoryEntryIdUtils {
Line 10: 
Line 11:     // ID is in format of "id=<UUID>:provider_name=<string>:<string>"
Line 12:     private static final Pattern ID_PATTERN =
Line 13:             
Pattern.compile("(id=)([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}):(provider_id=)(.+:.+)");
please always use named groups[1]

In your case it should be something like:

 (id=(?<id>.*)|(providerid=(?<provider>([^:]*):(?<provider_id>.*))

then you have group("id") != null for internal

and group("provider") != null && group("provider_id") != null for provider

no point to verify the uuid, as you simply won't find it in table.
