Description

When I have two authentication providers(database authentication provider and ldap authentication provider). At the first time, I login with an principal which is defined in the ldap, I can successfully login. For the second time, this user's authentication provider will change to the default database, cause J2 will create an mapping only principal in table SECURITY_PRINCIPAL. Of course, I fail to login.

I think it should not return the database authentication provider, it should return the real authentication provider.

I change the code in class: org.apache.jetspeed.security.spi.impl.SecurityAccessImpl
The orginal code:
    /**
     * <p>
     * Returns if a Internal UserPrincipal is defined for the user name.
     * </p>
     *
     * @param username The user name.
     * @return true if the user is known
     */
    public boolean isKnownUser(String username)
    {
        UserPrincipal userPrincipal = new UserPrincipalImpl(username);
        String fullPath = userPrincipal.getFullPath();
        // Get user.
        Criteria filter = new Criteria();
        filter.addEqualTo("fullPath", fullPath);
        Query query = QueryFactory.newQuery(InternalUserPrincipalImpl.class, filter);
        return getPersistenceBrokerTemplate().getCount(query) == 1;
    }

Code after I modified:
/**
     * <p>
     * Returns if a Internal UserPrincipal is defined for the user name.
     * The Jetspeed 2 implementation does not distinguish if this user
     * is a Mapping_Only user. I think we have to distinguish it cause it will
     * return the wrong Authentication Provider.
     *
     * An alternative solution is: we binding the username and Authentication Provider
     * for the first time login, then cache it in the memory or something,
     * then we don't need to change here.
     * </p>
     *
     * @param username The user name.
     * @return true if the user is known
     */
public boolean isKnownUser(String username) {
UserPrincipal userPrincipal = new UserPrincipalImpl(username);
        String fullPath = userPrincipal.getFullPath();
        // Get user.
        Criteria filter = new Criteria();
        // fullPath must be equal.
        filter.addEqualTo("fullPath", fullPath);
        // The isMappingOnly must not be true.
        // We don't need the mapping only user, mapping user can't be authenticated with this provider.
        // we just need the true user.
        filter.addEqualTo("isMappingOnly", Boolean.FALSE);
        Query query = QueryFactory.newQuery(InternalUserPrincipalImpl.class, filter);
        return getPersistenceBrokerTemplate().getCount(query) == 1;
}

Fix applied, thanks!
