Specifies the base distinguished
name (DN) of the directory service, which indicates the starting point
for LDAP searches of the directory service. In most cases, bind DN
and bind password are needed. However, when anonymous bind can satisfy
all of the required functions, bind DN and bind password are not needed.
For example, for a user with a DN of cn=John Doe , ou=Rochester, o=IBM, c=US,
specify the Base DN as any of the following options: ou=Rochester, o=IBM, c=US or o=IBM, c=US or c=US.
For authorization purposes, this field is case sensitive. This specification
implies that if a token is received, for example, from another cell
or Lotus® Domino®, the base DN in the server
must match the base DN from the other cell or Lotus Domino server
exactly.
