Richard,

Hello !

I'm looking at debian bug #466477.  Marc F. Clemente's problem discussed
in this bug should be resolved with the recent upload, which returns the
subject to your original report from February 19th.

Cool, some progress :)

We haven't been able to reproduce this.

Not surprising, the server is an IBM product, based upon older apache2
and openssl (not supporting newer TLS).

$ ldapsearch -x -Hldap://bluepages.ibm.com -b '' -sbase '(objectclass=*)' '*'

 Do you still have this problem?

Most definitely :(

$ dpkg -l libgnutls26
ii  libgnutls26    2.2.3~rc-1

$ gnutls-cli -p 636 bluepages.ibm.com
Resolving 'bluepages.ibm.com'...
Connecting to '9.17.186.253:636'...
*** Fatal error: A TLS packet with unexpected length was received.
*** Handshake has failed
GNUTLS ERROR: A TLS packet with unexpected length was received.

I'd like to close or downgrade the bug.

I'd rather not... I've had to rebuild openldap against openssl to
be able to operate in this environment - and there is a large number
of us using Debian - and I'm sure others who must live with an IBM
server in their environment.

Thanks for the follow-up, and let me know how I can help with this...
I can provide ldap/wireshark/etc traces if needed;  I'm guessing the
hand-shake error occurs as gnutls tries to check on TLS extensions,
but haven't spent much time on digging through the code.

I can't (I'd be canned, and its not my sever) expose the beast for
external testing, but I can run any diagnostics and report the results.
