I have to agree with Andy on this. I can’t see any point in ‘domain creep’, where Shibboleth enters your AD infrastructure. IdPs are clever enough to map institutional data to external facing formats such as eduperson. We occasionally need to use non eduperson attributes and the IdP just does it, based on data in AD.

tuppence dispensed, now skint.

Hi

 

I believe a few people did this, i.e. extended their schema, but I never really understood why you would want to do that.

 

The information which is used in the released eduperson attributes is there in our directory in other forms and it’s a fairly simple matter in attribute-resolver.xml to manipulate those into the form needed, for instance to create the staff/ student values for edupersonscopedaffiliation.   It would be a tautology to create another attribute in the directory and go to all the trouble of populating it.

 

EduPersonEntitlement values are usually kept in the form of group memberships which we can make easily manageable by, for example,  library staff, without them having to manipulate some very queer value,  and again the resolver can easily contain a scriptlet to test for group membership and set the required value to be released in ePE.

 

My tuppence.

Hi, 
 
I hope this is the right forum for my question.  I emailed Angel (LSE project –
[log in to unmask]) but my email bounced, so I guess it is no longer active.  
 
I administer Shibboleth IdPs and SPs at Queen's Universities (Library) and we are 
trying to present the case for enriching attributes within our directories with a 
view to implementing eduPerson.  
We are interested to know if many institutions  have implemented eduPerson schema
extensions in Active Directory (as opposed to mapping arbitrary values within the 
directories to eduPerson attributes).  I'm thinking of the methods described here 
at the Angel project site (section 2):
 
     http://www.angel.ac.uk/SECURe/deliverables/documentation/adconfig.html
 
Queen's are currently considering their options around eduPerson schema and Active
Directory in the medium to longer term.  Any information on the extent to which other 
institutions have implemented this in production systems would be very useful.
 
Thanks and Regards
Karen
