This attribute contains the internal "distinguished name" (DN) of the user's primary school in the home organizations user directory.
This attribute can be used in conjunction with the eduPersonOrgUnitDN to determine which of the eduPersonOrgUnitDN:mail, eduPersonOrgUnitDN:norEduOrgUnitUniqueIdentifier and eduPersonOrgUnitDN:ou attributes belongs to the user's primary school.
To determine the primary school's name, you need to find the index of the eduPersonPrimaryOrgUnitDN attribute in the eduPersonOrgUnitDN attribute. You can then look up the corresponding index in the eduPersonOrgUnitDN:ou attribute to determine the name.
Note: This attribute should not be used to identify the user's school, since it isn't unique across different organizations, and can be changed.
This attribute contains a single LDAP DN.
