These were logged during an attempt to login to Samba AD
It appears there's an issue with Dovecot authentication (or "pam")
but it may be elsewhere.
This is the instance where "dcerpc" calls from 'smb.conf' --
### Configuration required by OpenChange server ###
dsb:schema update allowed = true
dcerpc endpoint servers = +mapiproxy
dcerpc_mapiproxy:server = true
dcerpc_mapiproxy:interfaces = exchange_emsmdb, exchange_nsp,
exchange_ds_rfr
### Configuration required by OpenChange server ###
When I uncomment those "dcerpc" calls, Samba AD allows the first few
users to login then gives "Access denied" to the next users.
Curiously enough, even in that instance, Samba services are STILL
running.

I've *emboldened* the lines showing 'openchangedb' is not initiating.
It appears to err on '*exchange_emsmdb*' That's one of the "dcerpc"
calls in 'smb.conf'
--------------------------------------------------------------------------------------------------------------------------------------
sorry to be so late updating this issue, it is STILL unresolved
I uncommented the "dcerpc" calls in 'smb.conf' and restarted the server.
Samba services were running --
adam@sogo:~$ sudo initctl list | egrep 'samba|smb|nmb|winbind'
nmbd start/running
Something wrong here, nmbd shouldn't be running on a DC, how are you
starting samba ?
winbind stop/waiting
smbd stop/waiting
reload-smbd stop/waiting
samba-ad-dc start/running, process 841
adam@sogo:~$
What does 'ps ax' show ?
I could find no instance of OpenChange before or after starting
'openchange-oscmanager' --
I don't think it actually gets started as such, it is a samba module I
believe.
adam@sogo:~$ sudo ps aux | grep openchange
adam@sogo:~$
adam@sogo:~$ sudo ps -lA | awk '$12 == "?" {print $4, $14}' | grep
openchange
adam@sogo:~$
adam@sogo:~$ sudo service openchange-ocsmanager start
* Starting OCSManager application ocsmanager Entering daemon
mode [ OK ]
adam@sogo:~$ sudo ps -lA | awk '$12 == "?" {print $4, $14}' | grep
openchange
adam@sogo:~$
*How can I know whether OpenChange is running?*
It appears '*exchange_emsmdb*' is shutting down Samba services.
What is the requirement for encryption in regarding to running
OpenChange-OCSManager?
Any suggestions would be helpful. Is there an OpenChange forum?
No forum, but there is a mailing list.
