Hello,
I am looking very heavily on using zimbra over MS Exchange for a new organization (thats right, I have the rare opportunity of setting up an enterprise... from SCRATCH!).
I am currently utilizing LDAP and SMBLDAP-TOOLS as a back end to my samba domain. This same LDAP server is also used for UNIX authentication. Thus, my windows and unix accounts are fully SSO (Single Sign On) compliant.
I would like to maintain SSO compliancy and integrate zimbra as well. After reading through some of the posts on the forums (specifically the one about integrating samba), I sort of have an understanding on how to do this, but have some questions:

1. Does zimbra only store passwords in plain-text? Can I opt to use crypt or SSHA?
2. Can I change the zimbra password with external tools?

I am going to load a fresh box to do testing. I am assuming (from the documentation) that I should load ZIMBRA first and then use ZIMBRA's back-end LDAP database to store SMB and POSIX info. Correct?

Cheers,
Dave
