Clustering with multiple LDAP Base & RootDN

Hello,

I am looking to have a clustered set of ejabberd servers serving the same domain company.com at three different sites.

Each site has it's own unique AD Server, and thus a unique LDAP Base & RootDN to place in the LDAP Query. If I understand the responses to this question correctly (http://www.ejabberd.im/node/533), it is presently not possible to query multiple LDAP Base's and RootDN's.

However, I went ahead and set up individual servers at each site, and joined them in a cluster.

Relevant Configs from Site 1:
-------------
{auth_method, ldap}.
{ldap_servers, ["10.0.3.33","10.0.2.33"]}.
{ldap_uidattr, "sAMAccountName"}.
{ldap_base, "OU=Site 1 Employees,DC=site1,DC=company,DC=com"}.
{ldap_rootdn, "CN=messenger,CN=Users,DC=site1,DC=company,DC=com"}.
{ldap_password, "supersecret"}. % Password to LDAP manager
-------------
{hosts, ["company.com","messenger.site1.company.com"]}
-------------

Relevant Configs from Site 2:
-------------
{auth_method, ldap}.
{ldap_servers, ["10.0.2.33","10.0.3.33"]}.
{ldap_uidattr, "sAMAccountName"}.
{ldap_base, "OU=Site 2 Employees,DC=site2,DC=company,DC=com"}.
{ldap_rootdn, "CN=messenger,CN=Users,DC=site2,DC=company,DC=com"}.
{ldap_password, "supersecret"}. % Password to LDAP manager
-------------
{hosts, ["company.com","messenger.site2.company.com"]}
-------------

All this works as expected! I can have users at site 1 log in with their user information, and users at site 2 log in with theirs. (You cannot - as expected - log into site 1 with a login from site 2, and vice-versa)

But user1@company.com (from site1) can communicate with user2@company.com (at site2), and vice-versa, which is what I wanted.

Here's my question:

Is there anything particularly bad about setting things up this way? (The clustering docs say to make the ejabberd.cfg as identical as possible) Do I run the risk of corrupting databases, etc? Or is all this perfectly well and good?

Thanks in advance.
