Further testing with Andrew's kvm image shows the hang only occurs when C=
yrus=20
SASL's libsasldb2.so plugin is present. I always remove that
plugin from =
my=20
installs, since I only use in-directory SASL secrets. That's
probably why=
I=20
wasn't seeing the reported behavior before.
=20
Also a note - it's still not clear we've been talking about the same thin=
g up=20
to this point. Even when the samba test suite hangs, I see that
ldapsearc=
h=20
still works fine against slapd. At any rate, currently all of the
samba4 =
tests=20
pass for me.
Hmm. Using that KVM image, with the libsasldb moved aside (and with it
left in place), I still get errors. =20
However, there is an important difference: Where previously, once it
locked up nothing proceeded, now it proceeds - as if the failure is
temporary now. The error has changed too - instead of a failure to
connect, it is an inability to successfully read the rootDSE.=20
I agree, we might be jumping at different shadows here, but your patches
did fix something...
