No, you don't have to persist the whole JCR. Connecting to a database is
the same as connecting to a REST service. You just setup a data
connection in a Java class, same as you do with any database connection,
then read the /home/user info and push it into the database.Then, if you
change the user in the database, you still need to sync the information
into /home/users. If you search for SAML integration or LDAP
integration, that is basically what they are doing. /Ove
