User type - ACL settings

When you add a user or group to an ACL, you specify a user type for the entry in the ACL. A user type identifies whether a name in the ACL is for a person, server, group, or other entity. You assign a user type to a name to specify the type of ID required for accessing the database with that name.

You can designate an entry in the ACL as any of the following user types:

Unspecified
Select the Unspecified user type if you want to enable the name you are entering to access the database with any type of ID (Person, Server, or Group). The Default entry in an ACL is always assigned the Unspecified user type. IDs used to sign agents, such as Sametime® Development and IBM Notes® Companion Products, are also assigned the Unspecified user type when entered in a database ACL.
Person
Select the Person user type if the name you are entering belongs to a user who has a Person document containing a user name and Internet password in the Directory on the Sametime server or if the user has a Person entry in an LDAP directory on a third-party server.
Server
Select the Server user type if the name you are entering belongs to another server in the Domino® domain. When multiple servers are installed in a Domino environment, it might be necessary for a server to access data within the database or to replicate a database. Server names are frequently added to the pre-existing LocalDomainServers and OtherDomainServers server groups. The Server user type is generally used only if you have installed Sametime in a Domino environment. This user type performs the same function as it does on a Domino server.
Mixed Group
Select the Mixed Group user type if the name you are entering belongs to a group that consists of both Server and Person names.
Person Group
Select the Person Group user type if you are entering the name of a group that contains only people. You can enter a group from the Directory on the Sametime server, or you can enter a group stored in an LDAP directory on a third-party server in the ACL of a database.
Server Group
Select the Server Group user type if the name you are entering belongs to a group that consists of only servers.
