External authentication methods for logging in to a system can be used in SAP R/3. With One Identity Manager, you can maintain login data for logging in external system users, for example, Active Directory on an SAP R/3 environment.
You can use One Identity Manager to enter external user IDs and delete them.
To enter external IDs
-
Select the SAP R/3 > External IDs category.
-
Select the external identifier in the result list. Select the Change main data task.

Table 53: External ID properties
|
External user ID |
User login name for the user to log into external systems. The syntax you require depends on the type of authentication selected. The complete user identifier is compiled by template.
NOTE: The BAPI One Identity Manager uses the default settings RSUSREXT for generating the user identifier, which means that the user name is reset. The value provided in the interface is passed as prefix.
If you SAP R/3 environment uses something other than these default settings, modify the template for column SAPUserExtId.EXTID respectively. |

External identifier type |
Authentication type for the external user. This results in the syntax for the external identifier.
-
Distinguished Name for X.509: Login uses the distinguished name for X.509.
-
Windows NTLM or password verification with Windows domain controller: Login uses Windows NT Lan Manager or password verification with the Windows domain controller.
-
LDAP bind <user defined>: Login uses LDAP Bind (for other authentication mechanisms).
-
SAML Token: Authentication uses an SAML token profile.

Groups, roles, and profiles are mapped in the One Identity Manager, in order to provide the necessary permissions for user accounts. Groups, roles, and profiles can be assigned to user accounts, requested, or inherited through hierarchical roles in One Identity Manager. No groups, roles, or profiles can be added or deleted.
Groups
You can share maintenance of user accounts over different administrators by assigning user accounts to groups.
Roles
A role includes all transactions and user menus that an SAP user requires to fulfill its tasks. Roles are separated into single and composite roles. Single roles can be grouped together into composite roles. User account member in the roles can be set for a limit period.
Profiles
Access permissions to the system are regulated though profiles. Profiles are assigned through single roles or directly to user accounts. Profiles can be grouped into composite profiles.
You can edit the following data about groups, roles, and profiles in One Identity Manager:
- Assigned SAP user accounts
- Usage in the IT Shop
- Risk assessment
- Inheritance through roles and inheritance restrictions
- License information for system measurement

| Category |
Categories for group inheritance. Groups can be selectively inherited by user accounts. To do this, groups and user accounts are divided into categories. Select one or more categories from the menu. |
| Description |
Text field for additional explanation. |
