Re: [Samba] Update from el7.4 to el7.5 broke samba 4.6.14





Hi Rowland,

Yes, that's right (Thank you). Here is what happened:

On the DC's, libldb was this version on el7.4:
- libldb-1.1.29-2.el7_4.wing.x86_64 (from Wing's repo).

el7.5 brought in a more recent version:
- libldb-1.2.2-1.el7.x86_64
- libldb-1.2.2-1.el7.i686

What would be the best course of action here?
A) Downgrade el7.5 to libldb-1.1.29-2.el7_4.wing.x86_64?
B) rebuild samba-4.6.15 using Wing's src.rpm and keep libldb from el7.5
C) Upgrade to libldb-1.3.2-1.el7_10.wing.x86_64 (which I suspect would force me to update to samba 4.7 since they're both in 'extras').

I don't mind doing any of A), B) or C) but what would be the advice here? Is the upgrade path from samba 4.6 + libldb 1.1 to samba 4.6 + libldb 1.3 straightforward? I hope I done have to rebuild all of the DC's content (Don't want to do through RSAT again).

Any hints?

Many thanks for your time,

Vincent

Hi all,
After upgrading my first Samba AD DC from el7.4 to el7.5, I had the
pain of being greeted with a non-fonctional Samba. When I used
samba-tool, I was greeted with that message:

root@dc00 ~]# samba-tool dbcheck
ldb: module version mismatch
in ../source4/dsdb/samdb/ldb_modules/acl.c : ldb_version=1.2.2
module_version=1.1.29 ldb: failed to initialise
module /usr/lib64/samba/ldb/acl.so : Unavailable WARNING: Module
[samba_dsdb] not found - do you need to set LDB_MODULES_PATH?
Unable to load modules for tdb:///var/lib/samba/private/sam.ldb:
(null) ERROR: Failed to connect to DB at None.  If this is a really
old sam.ldb (before alpha9), then try again with --force-modules

What's the solution here? Rebuild the RPMS? stay on el7.4 until a new
rpm is released from Wing's repo?

Any hints welcomed,

Thank you,

Vincent


Have you upgraded libldb ?
