GROUP(5) File Formats Manual GROUP(5)NAME
group - group file
DESCRIPTION
Group contains for each group the following information:
group name
encrypted password
numerical group ID
a comma separated list of all users allowed in the group
This is an ASCII file. The fields are separated by colons; Each group is separated from the next by a new-line. If the password field is
null, no password is demanded.
This file resides in directory /etc. Because of the encrypted passwords, it can and does have general read permission and can be used, for
example, to map numerical group ID's to names.

group - group file
Description
The file is an ASCII file that contains the following information for each group:
Group name
Encrypted password
Numerical group ID
Comma-separated list of all users allowed in the group
Each group name is separated from the next by a new line. The fields are separated by colons. If the password field is null, no password
is demanded.
Because of the encrypted passwords, it can and does have general read permission and can be used, for example, to map numerical group IDs
to names.
The database can be distributed in a network by a naming service, such as Yellow Pages or BIND/Hesiod. See the Guide to the Yellow Pages
Service or the Guide to the BIND/Hesiod Service for setup information.
Restrictions
The command will not change the passwords.
Increasing the number of groups that a user is in beyond 8 can affect services that use SUN RPC. The version of SUN RPC shipped with ULTRX
V4.2 supports up to 32 groups. Prior versions supported users being in up to 8 groups. Users who increase the number of groups that they
are a member of to more than 8 will not be able to NFS mount file systems from ULTRIX servers older than V4.2. If root group membership is
increased to more than 8 groups on a V4.2 system, the YP service may not work if that V4.2 system is in a mixed YP server environment where
there are both V4.2 and previous releases of YP servers. Again, this incompatibility can only occur if a user's or root's group membership
is increased to more than 8 groups.
