Domino naming requirements

Refer to these guidelines when naming parts of the HCL Domino® system.

Note: Items marked with an asterisk (*) can include alpha characters (A - Z), numbers (0 - 9), dash (-), period (.), space ( ) , and underscore (_).

Table 1. Domino name and character requirements
NameCharactersTips
Domino domain31 maximumThis is usually the same as the organization name.

Use a single word, which can include the following characters:

  • alpha characters (A - Z)
  • numbers (0 - 9)
  • ampersand (&), dash (-) space ( ), or underscore (_)

You can also include international characters, but it is not recommended and they are not guaranteed to work.
Notes® named network 31 maximum
  • By default, the Server Setup program assigns names in the format port name network -- for example, TCP/IP network.
  • Edit Notes named network names to use an identifier such as the location of the HCL Notes named network and the network protocol -- for example, TCPIP-Boston.
Organization 3-64 maximum*
  • This name is typically the same as the Domino domain name.
  • The organization name is the name of the certifier ID and is appended to all user and server names.
Organizational unit 32 maximum*
  • There can be as many as four levels of organizational units.
Server255 maximumChoose a name you want to keep. If you change a server name, you must recertify the server ID. Also choose a name that meets your network's requirements for unique naming.

Use only the following characters

  • alpha characters (A - Z)
  • numbers (0 - 9)
  • ampersand (&), apostrophe (') dash (-) space ( ), underscore (_), or dot (.)

    Note: Starting in 12.0.2, to prevent a Domino server from allowing dots (.) and underscores (_) in Domino server names, you must use the notes.ini setting ADMIN_IGNORE_NEW_SERVERNAMING_CONVENTION=0 on the Domino server.


Keep in mind that Domino performs replication and mail routing on servers named with numbers before it does those tasks on servers named with alphabetic characters.
User255 maximum*Use a first and last name. A middle name is allowed, but usually not needed. User names can contain an apostrophe (').
Alternate userNo minimum Users can have only one alternate name.
Group255 maximumUse a single word, which can include the following characters:
  • alpha characters (A - Z)
  • numbers (0 - 9)
  • ampersand (&), dash (-), space ( ) , underscore (_), apostrophe ('), forward slash (/)

The at sign (@) and two forward slashes (//) are expressly prohibited.

Note: You can create groups with hierarchical distinguished names (DN). However, you must surround the forward slash (/) in a component value of a DN by surrounding it with double quotes. For example, 24"/"7 Support.

PortNo maximumDo not include spaces.
