The role name is the name an administrator uses to log in to a specific role.

Each role name must:

- be unique within a domain

- contain two to 32 letters, numerals, underscores (_), hyphens (-), and periods (.)

- begin with a letter

- have at least one lowercase letter

- not contain spaces

If you change this role name, the name of the mailing list associated with this role is automatically changed also.

Note: When you change the role name in an NIS domain, it may take a while before the owner of the home directory is changed to reflect the new name.
