+:ShibAffiliationAttribute
++++++++++++++++++++++++++
+
+The Shibboleth affiliation attribute holds information about the affiliation of the user (e.g. "OU") and is read from the DiscoFeed at each login. ``:ShibAffiliationAttribute`` is a name of a Shibboleth attribute in the Shibboleth header which Dataverse will read from instead of DiscoFeed. If this value is not set or empty, Dataverse uses the DiscoFeed.
+
+If the attribute is not yet set for the Shibboleth, please consult the Shibboleth Administrators at your institution. Typically it requires changing of the `/etc/shibboleth/attribute-map.xml` file by adding an attribute request, e.g.
+
+```
+    <Attribute name="urn:oid:2.5.4.11" id="ou">
+        <AttributeDecoder xsi:type="StringAttributeDecoder" caseSensitive="false"/>
+    </Attribute>
+```
+
+In order to implement the change, you should restart Shibboleth and Apache2 services:
+
+```
+sudo service shibd restart
+sudo service apache2 restart
+```
+
+To check if the attribute is sent, you should log in again to Dataverse and check Shibboleth's transaction log. You should see something like this:
+
+```
+INFO Shibboleth-TRANSACTION [25]: Cached the following attributes with session (ID: _9d1f34c0733b61c0feb0ca7596ef43b2) for (applicationId: default) {
+INFO Shibboleth-TRANSACTION [25]: 	givenName (1 values)
+INFO Shibboleth-TRANSACTION [25]: 	ou (1 values)
+INFO Shibboleth-TRANSACTION [25]: 	sn (1 values)
+INFO Shibboleth-TRANSACTION [25]: 	eppn (1 values)
+INFO Shibboleth-TRANSACTION [25]: 	mail (1 values)
+INFO Shibboleth-TRANSACTION [25]: 	displayName (1 values)
+INFO Shibboleth-TRANSACTION [25]: }
+```
+
+If you see the attribue you requested in this list, you can set the attribute in Dataverse.
+
+To set ``:ShibAffiliationAttribute``:
+
+``curl -X PUT -d "ou" http://localhost:8080/api/admin/settings/:ShibAffiliationAttribute``
+
+To delete ``:ShibAffiliationAttribute``:
+
+``curl -X DELETE http://localhost:8080/api/admin/settings/:ShibAffiliationAttribute``
+
+To check the current value of ``:ShibAffiliationAttribute``:
+
+``curl -X GET http://localhost:8080/api/admin/settings/:ShibAffiliationAttribute``
