141  * Formats of the output:
142  *
143  * Idmap reads/prints mappings in several formats: ordinary mappings,
144  * name mappings in Samba username map format (smbusers), Netapp
145  * usermap.cfg.
146  *
147  * DEFAULT_FORMAT are in fact the idmap subcommands suitable for
148  * piping to idmap standart input. For example
149  * add -d winuser:bob@foo.com unixuser:fred
150  * add -d winuser:bob2bar.com unixuser:fred
151  *
152  * SMBUSERS is the format of Samba username map (smbusers). For full
153  * documentation, search for "username map" in smb.conf manpage.
154  * The format is for example
155  *    fred = bob@foo.com bob2@bar.com
156  *
157  * USERMAP_CFG is the format of Netapp usermap.cfg file. Search
158  * http://www.netapp.com/ for more documentation. IP qualifiers are not
159  * supported.
160  * The format is for example
161  *    bob@foo.com => fred
162  *    "Bob With Spaces"@bar.com => fred  #comment
163  *
164  * The previous formats were for name rules. MAPPING_NAME and
165  * MAPPING_ID are for the actual mappings, as seen in show/dump
166  * commands. MAPPING_NAME prefers the string names of the user over
167  * their numerical identificators. MAPPING_ID prints just the
168  * identificators.
169  * Example of the MAPPING_NAME:
170  *   winname:bob@foo.com -> unixname:fred
171  *
172  * Example of the MAPPING_ID:
173  *   sid:S-1-2-3-4 -> uid:5678
