Hello,
Description of problem is as follows:
I have a email server package called Scalix, which when
installed came with openldap. On the same server i am also
running Stunnel, which is already successfully ssl wrapping
imap,pop, and smtp protocols. The ldap directory is very handy
for an address book internally but we also have people that will
be outside the corporate lan and to provide the directory
securely would be desirable so i added the lines in the
stunnel.conf to wrap ldap as well. I can see the stunnel daemon
listening on port 636. But when i try to connect from any ssl
aware mail client, such as evolution, or entourage, i get an
error indicating failure to authenticate, which i know is not
really the problem because the ldap directory is anonymous read
access enabled. Debug logging gives more information about what
is occurring, here is the conversion when attempting to connect:
2005.04.28 12:15:05 LOG5[27926:1076812720]: ldaps connected from
71.4.124.200:43012

2005.04.28 12:15:05 LOG7[27926:1076812720]: ldaps finished (6
left)
Searching the archive is saw someone suggesting that either the
ldap server or ldap client was not compiled with ssl support. I
know the email clients i am trying to connect with are ssl
compatible and maybe someone can set me straight here but i
didn't think that the ldap server had to be ssl aware and that
was the advantage of stunnel is that it can wrap services that
are do not have ssl support? At any rate i believe the ldap
server does have ssl support becuase i can see the binary
omslapd (provided by Scalix, preceding "om" is there because
Scalix is based on HP's Open Mail) links to the ssl library
using the ldd command, here is the output, note the bolded line:
