To configure default user preferences for a specific domain, for example, siroe.com, you need to do the following:
Create a directory with the name same as the domain name in <domain-dir> directory.
For example, create <domain-dir>/siroe.com directory.
Create a directory with the locale name inside the domain directory.
For example, if you want to have English locale for sireo.com, you must create a folder en in the domain directory. The directory structure would look as follows:
Copy uwcdomainconfig.properties file from <domain-dir> directory to the newly created directory above.
Make the required changes to uwcdomainconfig.properties file in<domain-dir>/siroe.com directory.
You can configure the default user preferences for global, calendar and address book.
Restart the web server to apply changes
