What OS are you upgrading on ? where did the old samba packages come 
from, your OS or inverse, where do think the new packages are coming from ?

I do not use sogo any more, more because of problems like this than 
anything else, I personally don't think openchange will get anywhere 
until you can install it on top of *any* version of samba4, not a 
specific version as at present. Having said that, if I check what 
'dcerpc endpoint servers' are running on my DC, I get this:

dcerpc endpoint servers = epmapper, wkssvc, rpcecho, samr, netlogon, 
lsarpc, spoolss, drsuapi, dssetup, unixinfo, browser, eventlog6, 
backupkey, dnsserver

So you only need to add 'mapiproxy' as 'epmapper' is already running.
