Shibbboleth IDP 3 Multiple Username Logins

[Raymond Gardner]

>>We are currently running Shibboleth IDP 3  using ldap for authentication.  We would like to be able to have users login with both their username (ex: jdoe) as well as their numerical username  (ex: 1111111) but resolving that value back to their regular username (jdoe).   Has anyone using shibboleth dealt with authenticating different usernames for a user?

I'm working on something similar.  User logs in with username1, we take that and lookup in the database a mapped username2.  Then, we use username2 to authenticate against LDAP.



Sounds like both your usernames are already in LDAP.  For us, I have to go to a database.  You might have more flexibility.



To do this, I'm using JAAS authentication.  It is more flexible and allows multiple sources.



I'm still working on my implementation.  I plan to extend the LDAPLoginModule from the ldaptive library so I may modify the incoming JAAS options.



I recommend looking into Ldaptive and the Shibboleth JAAS examples.  I believe their wiki for IDP2 has better JAAS documentation examples, but it is the same setup for IDP3.

For JAAS, the main configuration is in conf/authn/password-authn-config.xml.  This plus the JAAS config files.
