Sry if i made a double post but i can't find a really good answer: My Problem ist, that some of the Zimbra could use the publicKey Authentication and some of them not.
In Cleartext:

MTA could login with nopw: PROXY/LDAP
MTA couldn't login with nopws: mailbox

Proxy could login with nopw: LDAP
Proxy couldn't login with nopws: mta /mailbox

Mailbox could login with nopw: ALL

Ldap could login with nopw: ALL

* MY Zimbra Version is "Release 7.1.1_GA_3196.UBUNTU10_64 UBUNTU10_64 NETWORK edition."
* Every Server has the same OS-config (it was a template)
* I have no extra tules
* Made the final steps with "zmupdateauthkeys"
* Checked the .ssh/authorized_keys with the local zimbra_identity.pub (are the same)

Have someone the same troubles like me?!

Kind regards
