Subject Re: JNDI remote authentication problem
Date Thu, 08 Dec 2005 02:00:52 GMT
Vasily,
     I am currently looking into how well OpenEJB is obeying the
config.xmlfor setting its properties.  I think your issue could be a
side-effect of
GERONIMO-1151 located here:

http://issues.apache.org/jira/browse/GERONIMO-1151

As soon as I have this fixed, which has to be tonight, I'll be able to tell
you for sure if this is the case.

Take care,

Jeremy
