<h3 id="rzahyproxyauth">Proxy authorization</h3>
|
||
|
|
<p>The proxy authorization is a special form of authentication. By using this
|
||
|
|
proxy authorization mechanism, a client application can bind to the directory
|
||
|
|
with its own identity but is allowed to perform operations on behalf of another
|
||
|
|
user to access the target directory. A set of trusted applications or users
|
||
|
|
can access the Directory Server on behalf of multiple users.</p>
|
||
|
|
<p>The members in the proxy authorization group can assume any authenticated
|
||
|
|
identities except for the administrator or members of the administrative group.</p>
|
||
|
|
<p>The proxy authorization group can be stored under either localhost or IBMpolicies.
|
||
|
|
A proxy authorization group under IBMpolicies is replicated; a proxy authorization
|
||
|
|
group under localhost is not. You can store the proxy authorization group
|
||
|
|
under both localhost and IBMpolicies. If the proxy group is not stored under
|
||
|
|
one of these DNs, the server ignores the proxy part of the group and treats
|
||
|
|
it as a normal group.</p>
|
||
|
|
<p>As an example, a client application, client1, can bind to the Directory
|
||
|
|
Server with a high level of access permissions. UserA with limited permissions
|
||
|
|
sends a request to the client application. If the client is a member of the
|
||
|
|
proxy authorization group, instead of passing the request to the Directory
|
||
|
|
Server as client1, it can pass the request as UserA using the more limited
|
||
|
|
level of permissions. What this means is that instead of performing the request
|
||
|
|
as client1, the application server can access only that information or perform
|
||
|
|
only those actions that UserA is able to access or perform. It performs the
|
||
|
|
request on behalf of or as a proxy for UserA.</p>

<div class="notebody">The attribute

<p>Administrators and administrative group members are not permitted to be
|

members of the proxy authorization group. The audit log records both the bind

DN and the proxy DN for each action performed using proxy authorization.</p>
