[Pkg-openldap-devel] Bug#844282: slapd: postinst treats abort-upgrade as upgrade

[Ryan Tandy]

Package: slapd
Version: 2.4.40+dfsg-1
Severity: normal

slapd's postinst only considers install and upgrade cases (via 
is_initial_configuration), handling for others is missing.

Specifically, if postinst is called with abort-upgrade because preinst 
failed, the upgrade path is taken. This should be mostly harmless, but 
could cause some confusion: if 2.4.44's preinst fails, we back up the 
config in /var/backups/slapd-2.4.44; and when upgrading that to some 
other version later, we'll do it again. This could cause confusion if, 
for example, an overlay or database was deleted in the meantime: it 
would still be in the backup folder, it would still be in the backup 
folder, as the new backup is only copied over top.
