objectCategory is one of several special attributes in Active Directory
that allow several formats for searches. objectCategory allows both RDN
value and DN-based searches while being itself a DN.
This is documented in MS-ADTS 188.8.131.52.1.3.5:

This is covered in https://social.technet.microsoft.com/wiki/contents/articles/5392.active-directory-ldap-syntax-filters.aspx#Filter_on_objectCategory_and_objectClass
For groups there is not much difference but since objectCategory is
both single-valued and indexed, query with objectCategory will be more
efficient in AD DS.
