Subject: Fix #3284 about Client address not reloaded properly
X-Git-Tag: Release-9.0.6~11
X-Git-Url: https://git.sur5r.net/?p=bacula%2Fbacula;a=commitdiff_plain;h=53837608c90c789655a6ad4e8453dccca1705b9e

Fix #3284 about Client address not reloaded properly

The SetIpAddress and the Enabled flag was set systematically when
we create the global Client/Job/Schedule structure.

In fact, these variables must be set only with the enable/disable or
setip commands. Else, after a reload, new configuration values are not
used.
