[SSSD] [PATCH] Minor man page patches

[Jakub Hrozek]

Hi,

attached are three man page patches.

[PATCH 1/3] MAN: clarify the default access provider for AD
https://fedorahosted.org/sssd/ticket/1965

After we added a section that clarified what access_provider=ad did,
some users were confused and thought that "ad" was also the default
access provider if "id_provider=ad" was specified.

[PATCH 2/3] MAN: IP addresss does not work when used for ad_server
https://fedorahosted.org/sssd/ticket/1998

Currently using IP address as value of ad_server is not supported, so
the man pages should not mention that as an option.

[PATCH 3/3] MAN: Clarify the min_id/max_id limits further
https://fedorahosted.org/sssd/ticket/2005

Some users were confused by our description of min_id/max_id and thought
the limits only applied to returning entries from the NSS responder.
However, the limits are actually enforced on the back end side, so the
entries are not even saved to cache.
