CUP 8.6.4 Calendar Presence integration -> Authentication failure on server

Hi,

i have the following error from Presence Engine logs:

14:56:03.112 |system.pe.pa.owa.backend 1243662 ERROR -->EWSCalendarInfo::initiateRecovery: firstname.lastname@exchange.domain.com POST 3 Authentication failure on server; Could not authenticate to server: ignoring empty Negotiate continuation, rejected Basic challenge

In Presence the Exchange SSL Connection/Certificate Verification is Ok. Where is the problem? Any suggestions?

Regards

Jason

Re: CUP 8.6.4 Calendar Presence integration -> Authentication fa

I have now checked the Exchange logs:

From a working device which is unsing same impersonate account:

2012-09-05 00:00:04 192.168.100.10 POST /ews/exchange.asmx - 443 DOMAIN\Impersonateuser 192.168.50.34 ExchangeServicesClient/14.00.0650.007 200 0 0 234 

And from Cisco Presence with the same impersonate account:

2012-09-05 15:01:12 192.168.100.10 POST /ews/exchange.asmx - 443 - 192.168.90.100 - 401 1 2148074242 39

It seems cisco cup could not use the impersonate user account, its missing. But i have tried different formats in CUPs gateway options:

  • DOMAIN\Impersonateuser
  • DOMAIN.LOCAL\Impersonate-user
  • Impersonate-user@domain
  • Impersonate-user

Any suggestions?
