I can't log in to the jbpm console. The message shown is "Login failed. Invalid user name or password".
I use Sybase 15, JBoss 4.2.1, jbpm 3.2.1.GA web app and jbpm-enterprise.jar combined into my ear.

here is excerpt from my Sybase script:
2> set identity_insert JBPM_ID_GROUP on
3>
4> INSERT INTO JBPM_ID_GROUP (ID_,CLASS_,NAME_,TYPE_,PARENT_) VALUES(1,'G','admin','security-role',NULL)

There are no Exceptions thrown (I have the Exception breakpoint set up in Eclipse, and there are no helpful DUBUG level messages in the log). As I understand, there is some error reported by gravel, but I have no idea what is gravel, and can't find sources either.

I use security domain java:/jaas/jbpm; I tested SQL from my login-config.xml for jbpm application policy, it is fine and returns proper password and roles.
I have security roles 'user' and 'admin' set in web.xml, use FORM based authentication, enable security constrains for /sa/* for 'user'

May be, I have to change something in access.properties? I found no docs for this file.

Any thought welcome.

Thanks,
Vlad
