Chapter 7 Working With Users and Groups 57
An example user account looks like this:
jim:Adl47E$:408:20:J. Smith, Jr.,
M.D.:/Network/Servers/somemac/Homes/jim:/bin/csh
Using the StandardGroupRecord Shorthand
When the first record in a character-delimited import file contains
StandardGroupRecord, the following record description is assumed:
0x0A 0x5C 0x3A 0x2C DSRecTypeStandard:Groups 4
RecordName Password PrimaryGroupID GroupMembership
Here is an example of a record encoded using the description:
students:Ad147:88:jones,alonso,smith,wong
