[cisco-voip] CCMUser 6.x custom authentication

[Bill Simon]

We want to use a custom authentication scheme for CCMUser on CUCM 6.1.

We're running 4.1.3 now and have accomplished this by making a number of 
changes to the CCMUser site.  Not able to do this on 6.x.

Any thoughts on how to do custom authentication for CCMUser?  For 
authorization, we'd compare the logged-in (single-sign-on) username to 
the directory on CUCM.

Thanks,
Bill
