AD Connect for multiple Domains

Question

We need to have two different domains sync users with Sophos Central. 
 1 is already setup. We were going to add the other one of the server on the other domains, but because we have some names that overlap through both domains, we were advised that it would be better not to do this way and instead use filters to change query on the primary AD Sync. 
 I looked at the documentation and it's useless. 
 
 Can someone suggest how add two LDAPs to the same AD Sync? (Domains are in a two way trust)

Thank you!

Hi Felix Sky, 
 Which documentation are you referring to ? Could you please provide the link so that we can review it and update it accordingly ? 
 As for steps, please look at this document and let us know if any clarification is required: Sophos Central Admin AD Sync Utility filters Note: AD Sync Utility supports multiple domains; as a result it's important to remember that you may need to setup filters on each domain. 
 To set up the filters, please have a look at these steps 
 Regards,

I do not use Sophos Central at all, but I use UTM with multiple AD Domains by using an Activie Directory authentication server for the primary domain (which can only operate with unqualified domains) and LDAP for the additional domains (with qualified names.) 
 I wrote a cookbook for the process, which is posted in the UTM WiKi. I suspect that it will have some information that you will find helpful:
