Hi, thank you for the links! Now it works for me!
Here a little summary what I ve done - its very easy:
Login as zimbra user and move to the home-dir
Now your are in /opt/zimbra and can access the bin/zimbra-tools
First you ve to get the DataSourceId
You get an id like:
zmprov gds firstname.lastname@example.org | grep DataSourceId
Than you ve to run the following command
zmprov mds email@example.com fe1e635e-b42c-3a4d-f1b1-93aa4efe9bba zimbraDataSourcePollingInterval 600s
This is for a first step to activate some single users using zimbra version 6_06.
For a huge count of users this is not usefull, of course! Then a litte script was the next step. But for now this is not my part. Perhaps later
