Are you contacting OGSA-DAI using message level security? If so do
you have delegation set either limited to full? OGSA-DAI attempts to
uses your security credentials to contract the GridFTP server so you
must have specifying that you are allowing this delegation.

If you are using our client toolkit details of how to specify the
security are given in:
http://www.ogsadai.org.uk/documentation/ogsadai-wsrf-2.1/doc/clients/c
lienttoolkit/SecureServices.html

When using GridFTP I have always done so with an OGSA-DAI server that
is configured for security as described in:
http://www.ogsadai.org.uk/documentation/ogsadai-wsrf-2.1/doc/wsrf/depl
oy/Security.html

Regards,

Ally
