$ldap->modify question

[Mark M. <ma...@op...>]

I'm using perl-ldap-0.22 and I've notice something strange in my logs when I 
modify an entry. I'm using MessagingDirect LDAP/X500 product for my directory 
server.


$ldap->modify($dn, replace => { 'generationQualifier' => 'JR' });

If the 'generationQualifier' attribute doesn't exist, the logs show a successful 
modify to this entry. Not a problem.


$ldap->modify($dn, replace => { 'generationQualifier' => [] });

If the 'generationQualifier' attribute exists, the logs show a successful modify 
to this entry. Again, not a problem.


$ldap->modify($dn, replace => { 'generationQualifier' => 'SR' });

If the 'generationQualifier' attribute exists, the log first shows an "Error 
sent: Attribute" for the first attempt modify, followed by a successful modify 
to the record. 

I have not turned on full logging to see exactly what is being attempted twice 
and why the first always fails and the second succeeds. I wanted to see if 
anyone can tell me what the "ldap->modify replace" option is actually doing 
behind the scenes. I don't have a test server running so turning on the full 
logging on our production server is my last resort.


Any feedback would be greatly appreciated. Thanks.
