If you select files as your project database source in the nsswitch.conf file, the login process searches the /etc/project file for project information. See the projects(1) and project(4) man pages for more information.
The project file contains a one-line entry of the following form for each project recognized by the system:
The fields are defined as follows:
The name of the project. The name must be a string that consists of alphanumeric characters, underline (_) characters, hyphens (-), and periods (.). The period, which is reserved for projects with special meaning to the operating system, can only be used in the names of default projects for users. projname cannot contain colons (:) or newline characters.
The project's unique numerical ID (PROJID) within the system. The maximum value of the projid field is UID_MAX (2147483647).
A description of the project.
A comma-separated list of users who are allowed in the project.
Wildcards can be used in this field. An asterisk (*) allows all users to join the project. An exclamation point followed by an asterisk (!*) excludes all users from the project. An exclamation mark (!) followed by a user name excludes the specified user from the project.
A comma-separated list of groups of users who are allowed in the project.
Wildcards can be used in this field. An asterisk (*) allows all groups to join the project. An exclamation point followed by an asterisk (!*) excludes all groups from the project. An exclamation mark (!) followed by a group name excludes the specified group from the project.
A semicolon-separated list of name-value pairs, such as resource controls (see Chapter 6, About Resource Controls). name is an arbitrary string that specifies the object-related attribute, and value is the optional value for that attribute.
In the name-value pair, names are restricted to letters, digits, underscores, and periods. A period is conventionally used as a separator between the categories and subcategories of the resource control (rctl). The first character of an attribute name must be a letter. The name is case sensitive.
Values can be structured by using commas and parentheses to establish precedence.
A semicolon is used to separate name-value pairs. A semicolon cannot be used in a value definition. A colon is used to separate project fields. A colon cannot be used in a value definition.
This example shows the default /etc/project file:
system:0:::: user.root:1:::: noproject:2:::: default:3:::: group.staff:10::::
This example shows the default /etc/project file with project entries added at the end:
system:0:::: user.root:1:::: noproject:2:::: default:3:::: group.staff:10:::: user.ml:2424:Lyle Personal::: booksite:4113:Book Auction Project:ml,mp,jtd,kjh::
You can also add resource controls and attributes to the /etc/project file:
To add resource controls for a project, see Setting Resource Controls.
To define a physical memory resource cap for a project using the resource capping daemon described in rcapd(1M), see Attribute to Limit Physical Memory Usage for Projects.
To add a project.pool attribute to a project's entry, see Creating the Configuration.
