Mike,
I can confirm this behaviour.
DefaultPrincipalElectionStrategy was changed between 6.5 and 7.0. The change
was in 5bcef20 about 5 months ago.
The old behaviour was to select the first principle in a list; new behaviour
defaults to last.
Even setting this property,
cas.person-directory.principal-resolution-conflict-strategy=first
does not work.
Printing the list of principals immediately before
PrincipalElectionStrategyConflictResolver is invoked:
2024-04-11 23:40:23,144 ERROR [
org.aper.cas.auth.prin.DefaultPrincipalElectionStrategy] - <principal:
SimplePrincipal(id=rbon, attributes={cn=[Ray Bon], description=[ROLE_ADMIN],
domain=[uvic.ca], ...
2024-04-11 23:40:23,144 ERROR [
org.aper.cas.auth.prin.DefaultPrincipalElectionStrategy] - <principal:
SimplePrincipal(id=rbon, attributes={duoAud=[...],
duoAuthCtxAccessDeviceIp=[...], ...
The principal id's are the same (so merging attributes should work).
Our setup fetches attributes after authentication (instead of at the time of
authentication) but before duo flow.
I will investigate if there is an effect of when ldap attributes are retrieved;
as well as look into other possible config settings that might affect attribute
merging.

We are testing a CAS 7.0.3 POC system using universal prompt DUO MFA. The
system is configured to use OpenLDAP for authentication. However, once DUO MFA
is enabled via the Fawnoos blog entry, the attributes returned for the
principal are from DUO.
How do we tell CAS to only use the LDAP attribute repository?
Thanks,
Mike
