[Translators] VLC 2.1.0 - questions about strings

[Gonçalo Cordeiro]

Hello,

I'm updating VLC translation.

What "ident" means in that two strings ("identification" or a typo 
(indent))?:

#: modules/misc/logger.c:121
msgid "Syslog ident"
msgstr ""

#: modules/misc/logger.c:122
msgid "Set the ident that VLC would use when logging to syslog."
msgstr ""

Thanks in advance.
