[Pkg-sssd-devel] libldb1: wheezy backport breaks stock wheezy sssd

[Rolf Schirmacher]

Dear list,

I hope I will find the right point of contact this way...

The issue I have:

 > package: libldb1
 > Version: 1:1.1.17-1~bpo70+1
 > Severity: critical
 > Justification: breaks unrelated software
 >
 > Dear Maintainer,
 >
 > originally looking for a Sogo update, I installed samba from wheezy 
backports,
 > which includes the current libldb1 (i.e. 1.1.17).
 >
 > Unfortunately, the version handling of libldb1 is critical and there 
are packages
 > in stock wheezy that also depend on libldb1 and require 1.1.6 instead 
of 1.1.17 to work
 > properly.
 >
 > In my case, the package affected is sssd (not sure about other 
packages). sssd does not start up
 > with the libldb1 backport being installed and there is also no sssd 
(back)port available working with
 > the libldb1 1.1.17. As a result, regular users cannot log into the 
system any more (as that is managed
 > through sssd).
 >
 > I am not sure about how to resolve this best. One idea would be to 
offer backports / recompiled versions of
 > the affected packages (sssd, not sure about others) through backports 
and the dependency system?
 >
 > Thanks for any support on this issue.

and how it was closed as a bug:

which goes:

 > sssd is not "unrelated software": it depends on ldb. The ldb plugin 
ABI is
 > brittle and does not have any guarantees so downstream packages tend to
 > depend on specific ldb upstream versions, and thus need to be rebuilt
 > (binNMU) whenever a new ldb is uploaded.
 >
 > As per the FAQ, please report backport bugs to the backports mailing 
list.

Please keep me cc'ed on this topic as I don not regularily follow this 
list.

Thanks in advance for any support.
