one possible reason is that the DN of the requestor will make it easy for the recipient to retrieve his certificate and verify the signature

Hi,

In 7.3 of X.511 one might find the following text for the requestor
parameter of the CommonArguments:

The requestor Distinguished Name identifies the originator of a
particular operation. It holds the name of the user as identified at the
time of binding to the Directory. It may be required when the request is
to be signed (see 7.10), and shall hold the name of the user who
initiated the request.

Can anyone explain why the requestor component may be required when the
request is signed?

The text has been there unchanged since the very first edition. 7.10
does not give any clue as to why the component may be required.

Anyway, the requestor component is not very reliable for access control
requirements, as it is supplied by the originator. The identity
established during Bind is somewhat more reliable.
