  Selecting matching rule for compare operation?  Maybe I'm
missing something, but (unless the compare operation is to be
considered obsolete) there's a need for flexibility in
performing comparisons, e.g. a mech to select appropriate
matching rules when asserting values.  Scenario: want to know if
a server supports a certain control; supportedControl doesn't
define an EQUALITY rule; however, it's syntax is OID.
Quick'n'(not so)dirty: ldapsearch -b "" -s base
"(supportedControl:objectIdentifierMatch:=<OID>)" # if exactly
one entry is returned, the DSA supports the control  Clean
(would be) solution: ldapcompare ""
"supportedControl/objectIdentifierMatch:<OID>" # compareTrue if
value exists according to specified matchingRule  Is there a
better/more rfc-compliant way (other than defining an EQUALITY
rule for that attribute)?
