[Samba] Downgrading from 4.0.14 to 4.0.12

[Philipp v. Thunen]

Hello everyone,

as I'm experiencing massive trouble with 4.1.4 and 4.0.14 seems to 
be affected, too (https://bugzilla.samba.org/show_bug.cgi?id=10415),
I'm considering downgrading to 4.0.12 or 4.0.13 (via Sernet 
packages) because those were the versions running the most stable 
for me.

Is there any reason why this would not be advisable, except 
bugfixes that are introduced later, e. g. different db formats?

Thanks and regards
Philipp
