Oh I'm sorry, I missed this.

I use:
libldap2 version 2.1.30-3
LDAP-Server ist eDirectory (no idea of the version)
my platform is Debian-Linux kernel 2.4.24-1
openssl 0.9.6c-2.woody.7


The hardware should not be the problem because it works when I try
without SSL.

ldapsearch -D "cn=myuser,ou=myou,o=myo" -H ldaps://mydomain:636 cn=* -W
-x
Enter LDAP Password:
=>Segmentation fault

If I don't give the port, it gives the same error. 

gdb gives this:

Starting program: /usr/bin/ldapsearch -D "cn=mycn,ou=myou,o=myo" -H
ldaps://mydomain:636 cn=* -W

I hope I gave enough infos.
