Ticket #48143 - Password is not correctly passed to perl command line tools if it contains shell special characters.
Description: If a password contains shell special characters such as '$', '!',
'"', or ''', they were evaluated before passing to the core programs, e.g.,
ns-slapd for import and export or ldapmodify for tasks.
This patch escapes the special characters using shellEscape subroutine
Directory Manager Password: pas$w!or'd"
$ ./db2ldif.pl -n userRoot -D 'cn=directory manager' -w -w pas\$w\!or\'d\"
Successfully added task entry "cn=export_2015_4_7_15_17_16,cn=export,cn=tasks,cn=config"
