SimpleAggregation AttributeResolver and duplicate values

[Scott Koranda]

Hi,

I am using the Shibboleth SP 2.5.2 with the SimpleAggregation
AttributeResolver to query an attribute authority (AA) distinct
from the IdP used for authentication.

For some attributes both the IdP and the AA are asserting the
same value leading to duplicate values in the corresponding
Apache environment variable. For example

givenName Scott;Scott
sn        Koranda;Koranda

Is the Transform AttributeResolver a vehicle for removing the
duplicate values or should I deal with this at the application
layer?

Thanks,

Scott K
