Hi Massimo,

Dear all,
I am experiencing the following problem in GT4.0.5 using the prews
GRAM.
If my server tries to refresh the credentials for a long running
job before the proxy expires (it uses its own host credentials), it
gets back the following error from the jobmanager: an
authentication operation failed. However, I am sure that the
credential used is valid and is correct because the server is
downloading a fresh proxy from a MyProxy server, and the credential
is obtained through gss_import_cred(). After importing the
credential, it is checked using gss_inquire_cred(),
gss_display_name() etc to validate the distinguished name and the
credential lifetime.
I am using the gcc32dbgpthr flavor, and refreshing the credentials
using globus_gram_client_register_job_refresh_credentials().
In particular, besides setting the credential to be used as the
second argument, I am also setting the third argument which is the
globus gram client attribute. The attribute is at first initialized
using globus_gram_client_attr_init(), then I use
globus_gram_client_attr_set_credential() to set for the attribute
the same credential I will use for the refresh operation (the same
used for the second argument).
I am sure that the distinguished name associated to the credential
is in the remote machine grid-mapfile and is authorized (the same
proxy downloaded from Myproxy is ok to submit a job to the remote
machine). I am also sure that the jobid (the irst argument of the
globus_gram_client_register_job_refresh_credentials() function) is
correct (using globus-job-status I see the job is active).
The same code was working without any problems in previous GT
releases.
Any clue about?
I am i doing something wrong due to changes in the GT4.05 prews GRAM?
Thank you in advance,
Massimo
