[Dovecot] User mapping via pam

Hi,

I'm trying to change the PAM_USER within a pam module, and observed that dovecot 0.99 does not support this. I then looked at 1.x and found:

src/auth/passdb-pam.c:232:

    /* FIXME: this doesn't actually work since we're in the child

       process.. */

    status = pam_get_item(pamh, PAM_USER, (linux_const void

**)&item);

    if (status != PAM_SUCCESS) {

            *error = t_strdup_printf("pam_get_item() failed: %s",

                                     pam_strerror(pamh, status));

            return status;

    }

    auth_request_set_field(request, "user", item, NULL);

however it appeared to me that the auth process was passing this username to the parent in its response.

Is this issue resolved? I compiled and tested mapping the username sso to the user andrew:

Jun 27 13:38:45 itsrv dovecot: auth-worker(default): pam(sso,10.x.x.x): lookup service=imap

Jun 27 13:38:45 itsrv dovecot: auth(default): auth(sso,10.x.x.x): username changed sso -> andrew

Jun 27 13:38:45 itsrv dovecot: auth(default): client out: OK 1 user=andrew

Jun 27 13:50:57 itsrv dovecot: auth(default): master in: REQUEST 1 19761 1

Jun 27 13:50:57 itsrv dovecot: auth(default): passwd(andrew,10.x.x.x): lookup

Jun 27 13:50:57 itsrv dovecot: auth(default): master out: USER 1 andrew system_user=andrew uid=1001 gid=1001 home=/home/Andrew

Also, is this behavior dependant on me setting blocking=yes for "passdb pam" in dovecot.conf? (for this test It was set)

Thanks,
