LDAP with same name accounts created in Zimbra

[grantntourbus]

Running Zimbra 8.8.10 on CentOS 7. Going to upgrade to 8.8.15 soon.

I would like to connect to our Windows AD using LDAP, but have already created all the email accounts in Zimbra.
If I connect the Zimbra LDAP to AD, what will happen to accounts pre-existing in Zimbra, with similar email addresses?
I have Zimbra setup as a secondary, with Exchange as the primary.

Example: Say I have a Zimbra account, Fred@host.com and a Windows AD user domain\Fred with Exchange email account Fred@host.com.

What can I expect when I enable the connection to LDAP?
Can anyone point me to more information on what the LDAP connection does in Zimbra?

The reason I did not setup LDAP right at the start, is I needed to test the migration with a limited number of accounts first, so I did not want all my domain accounts in Zimbra right off the start.

Hi, with LDAP connection your users will be able to connect to their Zimbra mail account using AD password.
Here is Zimbra documentation on this topic: https://wiki.zimbra.com/wiki/Configure_ ... _Directory
