I've had similar results with 2.2.4, but with 2.2.3, option b did
partially work, IIRC (perhaps with DBDPersist Off?).
Even when it works, I've found it unreliable. I have three
subdirectories which require the same authentication (the authn config
is "Include"d from the same file), and I keep being asked for new
credentials as I moved between them, and sometimes the creds are
rejected several times. There is no such problem with the parallel
2.0.52 installation (using mod_auth_mysql) which I'm trying to migrate from.
If it's any help to anyone, I think I managed to trace the "No DBD..."
error some way, though I can't be sure of the precise circumstances. In
one case (perhaps with DBDPersist Off), in the file
"modules/aaa/mod_authn_dbd.c", the function "authn_dbd_password" calls
"apr_hash_get", which returns NULL.
In another case (DBDPersist On?):
* authn_dbd_password calls...
* authn_dbd_acquire_fn, which appears to be indirectly a call to...
* ap_dbd_acquire, which calls...
* ap_dbd_open, ...
* dbd_setup_lock...
* apr_thread_mutex_lock, which fails.
Cheers,
Steven
