Hello, today I upgraded one of my DCs to Ubuntu to 20.04.1. After that my DC did not work anymore, despite unmasking, reenabling. In /var/log/samba/log.samba I get the error messages below. Looks like libraries are missing. What shall I do? Thanks, Joachim root at cobra:/var/log/samba# cat log.samba [2020/10/11 15:12:51.009065, 0]

Although the real reason for adding the new interface is the vddk plugin, that one is harder to test (not everyone configures it to be built); so adding a standalone plugin that does the bare minimum to validate our code is worthwhile.

I've got a situation where I need to hook a dlopen() made by VDDK, a proprietary library, where it passes a relative name expecting to resolve to a copy of several libraries, including libstdc++.so, that it installs alongside itself, and fails to load if that resolves to the system libstdc++.so. The simplest solution of providing LD_LIBRARY_PATH is enough to load VDDK, but then poisons

Differences from v4: Patch 1 is simplified: I realized that since we already use -rdynamic for nbdkit (after all, we WANT our dlopen()d plugins to be able to call our nbdkit_* exports), it is only a matter of adding dlopen to the set of symbols that we export. With that done, there is no separate shared library needed; our dlopen shim is now part of nbdkit proper, and we don't have to tweak

I'm a lot happier with this version: no mucking with dlmopen(). It does add a bit more coupling between nbdkit proper and the vddk plugin (namely, nbdkit now exports a new function that the vddk plugin relies on), but patch 2 adds testsuite coverage of the new function so we shouldn't regress. Patch 1 and 2 are new, patch 3 is unchanged from when Rich posted it in v2, and patch 4 is

From: "Richard W.M. Jones" <rjones@redhat.com> Do not use LD_LIBRARY_PATH to locate the VDDK library. Setting this always causes problems because VDDK comes bundled with broken replacements for system libraries, such as libcrypto.so and libstdc++.so. Two problems this causes which we have seen in the real world: (1) User does ‘export LD_LIBRARY_PATH=vmware-vix-disklib-distrib’

Hi, i upgraded my domain controller (dc1 and dc2, Ubuntu 18.04, compiled version of samba). It was a in-place upgrade from samba 4.11.7 to 4.12.3 Now I get the following error: # samba-tool drs showrepl ldb: unable to dlopen /usr/local/samba/lib/ldb/local_password.so : /usr/local/samba/lib/private/libsamdb-common-samba4.so: version `SAMBA_4.11.7' not found (required by

Hi, I'm trying to replace my current samba4/bind setup with Tridge's new DLZ bind method (s. http://blog.tridgell.net/?p=122). Instructions about how to set this up seem a little rare right now, and I'm not even sure wether this is supposed to work at all in its current state (but I'll give it a try anyway :-) What I found so far: In order to use the new dlopen DLZ you'll

Dear Dovecot users/devs, I have the following mbox file: /tmp/dsync_test/mbox/2002-September I would like to convert it to a Maildir: /tmp/dsync_test/maildir (Currently, the latter is just an empty directory.) I am attempting this on an old PC running Debian 9 ("Stretch"). I installed the dovecot-core package in order to make the `dsync` tool available on that PC. I have
