I've got a pre-existing install of ZCS 6 running as an all-in-one server. We'd like to move the mail store to another server and keep the existing server as the MTA.
I am intalling ZCS on the secondary server and can't get the replication password to change on the master.

root@zimbra:/opt/zimbra/bin# sudo -u zimbra ./zmldappasswd -l mypassword
Updating local config and LDAP
TLS: SSL connect attempt failed with unknown errorerror:0407006A:rsa routines:RSA_padding_check_PKCS1_type_1:block type is not 01

Any ideas about this error?

I'm not sure what the root ldap password was set to, probably whatever default was. If I do:

sudo -u zimbra ./zmldappasswd -r mypassword

on the master, will this mess up my current server? I just want to make sure I don't take my running mail server down.
On my slave server I'm still stuck at the config page waiting to verify the LDAP Admin password and the LDAP replication password.
Also, I've already enabled replication on the master.
