Hello,

This bug report was reproduced with the following; I have several domains that include the letter 's' and ones without.

The ones without successfully backup, however the ones with 's' did not.

I remedied the issue by changing the following in ListAction.sh file:

for i in ${4//\n/g}; do

Not certain if it will break other logics on your script, but it passed correctly the domain with 's' to the ldapsearch command.

hope this helps.

it also breaks if there is an "n" in the email adress because it gets substituted with g. "\s" and "\n" does not not work with bash substitution. you can check out the proper fix here: https://github.com/tofuSCHNITZEL/zmbackup/commit/d5028344feb83342d73e5977dfc138c404a913cc
