You can link up an account with a local entity.  Here is an example from the demo server

Add a user via apache like the previous link: test_local_entity

[mchyzer@i2midev1 ~]$ sudo htpasswd /etc/httpd/conf.d/users.pass test_local_entity
New password: 
Re-type new password: 
Adding password for user test_local_entity

Create the local entity in Grouper.


Add it to the WS group


configure a prefix on logins on WS: in grouper-ws.properties

# prepend to the userid this value (e.g. if using local entities, might be:    etc:servicePrincipals:   )
ws.security.prependToUserIdForSubjectLookup = etc:servicePrincipals:


Hit a link:  login as   test_local_entity   and    whatever_pass
