Although useradd and groupadd complain about long names, neither them nor long ids seems to hurt ls with Solaris:
Code:
$ pfexec groupadd -g 2147483647 biggroupbiggroupbiggroupbiggroup
UX: groupadd: biggroupbiggroupbiggroupbiggroup name too long.
$ pfexec useradd -u 2147483647 -g biggroupbiggroupbiggroupbiggroup biguserbiguserbiguserbiguser
UX: useradd: biguserbiguserbiguserbiguser name too long.

groupadd(1M)						  System Administration Commands					      groupadd(1M)

NAME
groupadd - add (create) a new group definition on the system SYNOPSIS
/usr/sbin/groupadd [ -g gid [-o]] group DESCRIPTION
The groupadd command creates a new group definition on the system by adding the appropriate entry to the /etc/group file. OPTIONS
The following options are supported: -g gid Assigns the group id gid for the new group. This group id must be a non-negative decimal integer below MAXUID as defined in /usr/include/sys/param.h. The group ID defaults to the next available (unique) number above the highest number currently assigned. For example, if groups 100, 105, and 200 are assigned as groups, the next default group number will be 201. (Group IDs from 0-99 are reserved by SunOS for future applications.) -o Allows the gid to be duplicated (non-unique). OPERANDS
The following operands are supported: group A string consisting of characters from the set of lower case alphabetic characters and numeric characters. A warning message will be written if the string exceeds MAXGLEN, which is usually set at eight characters. The group field must contain at least one character; it accepts lower case or numeric characters or a combination of both, and must not contain a colon (:) or NEWLINE. EXIT STATUS
The following exit values are returned: 0 Successful completion. 2 Invalid command syntax. A usage message for the groupadd command is displayed. 3 An invalid argument was provided to an option. 4 The gid is not unique (when -o option is not used). 9 The group is not unique. 10 The /etc/group file cannot be updated. FILES
/etc/group /usr/include/userdefs.h ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO

groupadd only adds a group definition to the local system. If a network name service such as NIS or NIS+ is being used to supplement the local /etc/group file with additional entries, groupadd cannot change information supplied by the network name service. However, groupadd will verify the uniqueness of group name and group ID against the external name service. SunOS 5.10 27 Mar 1998 groupadd(1M)
