What could be done is:
1) user in DSPace is assigned to pseudonym as identifier (e.g. using netid)
2) user has his email address being "updated" from shibboleth (hence if he
changes email, it will be reflected right away)
I think this will satisfy your requirements (whereby there is a chance for user
to change his email address), however this requires a guarantee that the user
never changes his pseudonym (or netid).
We have chosen early in the development of the patch to stick to 1 attribute
(email) for both options 1 & 2. This simplifies matters cause rarely users
change their email address (as long they have associations with their IdP).
This also because we realized that some IdPs may not be able to supply unique
netid (or whatever attribute, eg. targeted id) for option #1, hence using email
address was considered sufficient.
Having said so, it will be fairly simple to put netid or other attributes as
pseudony identifier. Portability of netid or targetedID (which is not supported
by the attribute definition itself) in repository world is yet to be addressed
though....In AU, we have sharedtoken attribute, which is a unique identifier
permanent for every individual in the federation, this can be used when
portability is required, but otherwise we still encourage the usage of
targetedid.
Anyway, we should be able to post new patch containing option for netid next
week (if you can wait till then), feel free to make use of it :)
Hope that helps,
Bruc

Subject: Re: [Dspace-tech] pseudonym vs email-address
Hi.
I can only speak for v1.4.2, but I don't think it is much different for
1.5.x: as email is a column of of eperson table (which also gets a
eperson_id column), why couldn't you change the email value, instead of
using a pseudonym.
This would be better if the user could change the email himself.
