Subject: System apparently hangs during $ldap->bind();
I'm trying to do a simple connect to a our new ldap server at work.
It's the right server, right port, ldap is running, gq can access the
data with the same dn, but when I connect bind gets an anwser and then
apparently the script hangs.
I'm using Net::LDAP 0.2701 on Win NT 4.0 with Activestate Perl 5.6.0
(build 613) LDAP server is an HPUX11 with OpenLDAP 2.1.3.
debug=3 delivers this:
Net::LDAP=HASH(0x98b082c) sending:
30 1C 02 01 01 40 17 02 01 02 04 0A 63 6E 3D 6D 0....@......cn=m

Unexpected PDU, ignored
This is the point where the system seams to hang.
What is going wrong? Any hints would be very helpfull.

That's an illegally encoded bind operation. I think Convert::ASN1's failing
to set the constructed bit for the "[APPLICATION 0]" element. (The sixth
byte should be 60, not 40.)

That's an LDAPv3 "notice of disconnection" message with a result code of
operationsError. Servers send those messages if the client's sending them
crud (like bad protocol), though there's actually a different result code
for protocolError.

That's Net::LDAP not being able to cope with the notice of disconnection!

Yup, the server's probably closed the socket and your packets are bouncing
around the LAN until TCP times out (5 minutes IIRC).

Looks like a Convert::ASN1 bug. This has a problem on perl 5.8 systems when
the default locale is utf8, so I wonder if this is the same problem? I don't
know how you'd test (or change!) that in ActiveState Perl + Windows.
