Multi-Valued Attributes in LDAP

When setting or retrieving multi-valued attributes in an LDAP user store, the values are presented in a single string, delimited by a carat character ( ^ ).

For example, you might set three different telephone numbers as follows:

char lpszTemp[] = "111-1234^111-5678^111-0000";

int getResult = lpUserContext->fSetProp (lpUserContext->lpParam,
                                         "telephonenumber",
                                         strlen(lpszTemp),
                                         lpszTemp);

Custom code that sets or retrieves multi-valued attributes must support the expected multi-valued string format.

Note: ODBC user stores do not support multi-valued attribute settings.

Policy Server Version Support

With a 4.61 or later Policy Server, the telephone numbers in the example above are put into the user's telephone number attribute in the LDAP user store as follows:

111-1234
111-5678
111-0000

Prior to the 4.61 Policy Server, the above code would set the telephone number attribute as follows:

111-1234^111-5678^111-0000
