Resetting LDAP & MySQL Passwords
By far, one of the most common problems in getting a service started is an incorrect password.
Resetting the LDAP Password
First, we need to make sure that Zimbra is stopped.
Try running: >su zimbra >zmcontrol stop
Just to be safe, you can make sure that all Zimbra services are stopped: >ps auxww | grep zimbra >ps auxww | grep slapd
Kill any left over processes.
Now, we can reset the passwords:
First the root(note: these are run as user zimbra)
>zmldappasswd --root newpass
Next the zimbra: >zmldappasswd newpass
Make sure you use the same password for both!
