Hi
No...
I would probably leave the CCM using the internal user DB. That way you have control; you don't want to give any control to the customers over what happens to your cluster, as that may easily impact other customers.
For example, I don't know what you use for your username format on CCM... but if you link to AD, you have to use one of a few fields:
sAMAccountName
telephoneNumber
etc..
Normally with AD, the sAMAccountName is unique - with 5 customers, it may well not be. If they overlap (i.e. two users named john in different companies) you then have a problem.
The directory on the phones and the directory in CCM (whether statically configured, or LDAP synced) are usually one and the same, but this doesn't have to be the case.
You can create a directory service, which is configured to look at Customer 1's AD.
Create another for Cust 2.
Etc...
Then point each companies phones' Directories URL at their directory.
You would have some other concerns:
- If you host this at your premise, you'd need access to their AD to do the search
- You could allow them to host their own directory service, if you're happy to do that.
- You need to write the directory service (or steal one, see this URL for one I posted up: https://supportforums.cisco.com/message/3026015#3026015)
They would need to ensure whatever LDAP field you use are populated with correct numbers, but then.. they'd probably need to do that anyway. Of course, you may have customers that don't use AD...
