Hi,

I installed Openldap 2.4.11-1 on two Debian Lenny servers (srv3, srv4), in mastrer-slave configuration. I wanted to create secure connection for syncrepl.
srv3 is the master (provider) and srv4 is the slave (consumer). While I didn't use secure connection, the ldapsearch, and syncrepl worked. After I set up secure connection, syncrepl didn't work.
I start slapd with  -h ldap://127.0.0.1/ ldaps:/// on both servers.

ldapsearch partially works:
Works from srv3:
ldapsearch -H ldaps://srv3.mydomain.site:636 -W -x -D "cn=adm,dc=mydomain,dc=site" -b "dc=mydomain,dc=site" "(ObjectClass=*)"
ldapsearch -H ldaps://srv4.mydomain.site:636 -W -x -D "cn=adm,dc=mydomain,dc=site" -b "dc=mydomain,dc=site" "(ObjectClass=*)"
ldapsearch -H ldap://127.0.0.1:389 -x -W -D "cn=adm,dc=mydomain,dc=site" -b "dc=mydomain,dc=site" "(ObjectClass=*)"

Works from srv4:
ldapsearch -H ldaps://srv4.mydomain.site:636/ -W -x -D "cn=adm,dc=mydomain,dc=site" -b "dc=mydomain,dc=site" "(ObjectClass=*)"
ldapsearch -H ldap://127.0.0.1:389 -x -W -D "cn=adm,dc=mydomain,dc=site" -b "dc=mydomain,dc=site" "(ObjectClass=*)"

_Doesn't_work_from_srv4_:
ldapsearch -H ldaps://srv3.mydomain.site:636/ -W -x -D "cn=adm,dc=mydomain,dc=site" -b "dc=mydomain,dc=site" "(ObjectClass=*)"
Enter LDAP Password:  *(after i give the password, it waits 1-2 seconds)*
