Ongoing problems with TLS it seems

[David Harrison <david.harrison@sensorynetworks.com>]

Hi all,

I've been getting these errors recently (since a libldap upgrade I
think) and it is becoming quite frustrating.  It is happening to any
service that uses ldap for resolution (nss, mail, samba etc).

The platform is Debian Stable (sarge) with :

Pkg : libldap-2.2-7, Version : 2.2.23-8
Pkg : libgnutls11  , Version : 1.0.16-13.1
Pkg : libsasl2     , Version : 2.1.19-1.5

The server end is the same platform with :

Pkg : slapd        , Version : 2.2.23-8

I've found a few posts that indicate it is a bug in libldap, can anyone
confirm or deny this for me ?

How can I help fix this ?

I've got a gdb transcript below,

Thanks
Dave
