A problem has shown up with the decoding of the AttributeValue for the 
"netlogon" attribute in a CLDAP response.  This problem showed up sometime
after Wireshark 1.3.5.  I tested using 1.4.0 and 1.5.0-34154 and both showed
the same failure.

I'm attaching a capture to this bug report.  The following examples are showing
the response in frame 4 in the capture.

In Wireshark 1.4.0 and 1.5.0-34154 the decode of frame 4 looks like:

Connectionless Lightweight Directory Access Protocol
    LDAPMessage searchResEntry(1) "<ROOT>" [1 result]
        messageID: 1
        protocolOp: searchResEntry (4)
            searchResEntry
                objectName: 
                attributes: 1 item
                    PartialAttributeList item netlogon
                        type: netlogon
                        vals: 1 item
                            AttributeValue:
17000000fd03000057a2d80c69f5b846b1c6ed6dcf21d199...

The correct decode should look like:

Connectionless Lightweight Directory Access Protocol
    LDAPMessage searchResEntry(1) "<ROOT>" [1 result]
        messageID: 1
        protocolOp: searchResEntry (4)
            searchResEntry
                objectName: 
                attributes: 1 item
                    PartialAttributeList netlogon
                        type: netlogon
                        vals: 1 item
