The demo user "grover" cannot log into the web console.

The file \jbpm-jpdl-3.2.Beta2-suite\server\server\jbpm\data\hypersonic\jbpmDB.script holds, among many other lines:

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(1,'M',NULL,NULL,2,2)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(2,'M',NULL,NULL,2,4)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(3,'M',NULL,NULL,1,4)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(4,'M',NULL,NULL,3,4)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(5,'M',NULL,NULL,3,3)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(6,'M',NULL,NULL,2,3)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(7,'M',NULL,NULL,2,5)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(8,'M',NULL,'boss',2,1)
INSERT INTO JBPM_ID_MEMBERSHIP VALUES(9,'M',NULL,NULL,1,1)
INSERT INTO JBPM_ID_USER VALUES(1,'U','cookie monster','cookie.monster@sesamestreet.tv','cookie monster')
INSERT INTO JBPM_ID_USER VALUES(2,'U','ernie','ernie@sesamestreet.tv','ernie')
INSERT INTO JBPM_ID_USER VALUES(3,'U','bert','bert@sesamestreet.tv','bert')
INSERT INTO JBPM_ID_USER VALUES(4,'U','grover','grover@sesamestreet.tv','grover')

Fix:

To allow Grover to login, this also needs

INSERT INTO JBPM_ID_MEMBERSHIP VALUES(10,'M',NULL,NULL,4,4)
