The branch, v3-6-test has been updated
via 5bc0db4... Fix bug #7589 - ntlm_auth fails to use cached credentials.
from 749b946... Fix tdb_check() to work with read-only tdb databases. The function tdb_lockall() uses F_WRLCK internally, which doesn't work on a fd opened with O_RDONLY. Use tdb_lockall_read() instead.

commit 5bc0db425f71ec8b7a570294b04cb2fb6d27be69

Fix bug #7589 - ntlm_auth fails to use cached credentials.
In handling the WINBINDD_PAM_AUTH message winbindd canonicalizes a *copy*
of the mapped username, but fails to canonicalize the actual username
sent to the backend domain process. When "winbind default domain"
is set this can lead to credentials being cached with an index of
user: user, not DOMAIN\user. All other code paths that use
canonicalize_username() (WINBINDD_PAM_CHAUTHTOK, WINBINDD_PAM_LOGOFF)
correctly canonicalize the data sent to the backend. All calls
the can cause credentials to be looked up (PAM_CHAUTHTOK etc.)
correctly call canonicalize_username() to create the credential
lookup key.
Jeremy.
