[keycloak-dev] LDAP Federation & Subject ID's

Hiya One of our projects is looking to tie Knox and Keycloak together; with some documentation here https://community.hortonworks.com/articles/196751/knox-accept-third-party.... At the moment the users are being federated to an ldap user store. The issue at the moment is the subject ID, they would like this mapped 'uid' attribute to the user representation in ldap, is this simply a matter of changing the 'UUID LDAP attribute' .. They did try and they started getting errors logging in, I'm guessing this was perhaps due to changing the mapping once users had already been imported? ... Alas, I don't have access to components myself, so acting as a middle man at the moment Rohith
