SPNEGO on the appliance
I have installed the appliance (zca-18.104.22.1687) for a proof of concept and it works fine so far on vSphere 5u1 and I setup a single domain with LDAP auth against AD with no problems.
I attempted to follow the instructions in the admin guide to enable SPNEGO authentication - we use Kerberos a lot on Windows/Linux workstations. However I now get an Internal Server Error ERROR 500 in the browser when logging in.
I then tried to enable the debugging options suggested in the guide. The details are a bit vague in the docs but it seems I should put this in /opt/zimbra/conf/localconfig.xml
and add a line to /opt/zimbra/conf/log4j.properties.in (the docs say without the .in but that file is generated at the service start up and overwritten)
The localconfig change causes the Zimbra system to fail to start up. The extra logging seems to cause this:
I have double checked the settings using zmprov and they all look correct against the doc examples.
I'd be grateful for some directions on getting this working.
Just got the same problem here.
First, make sure your SSO configuration is correct by pointing your browser to <zimbra server>/service/spnego/snoop.jsp. If successful, this will give you all the information about the authentication.
Then, try the follolwing URL: <zimbra server>/service/spnego/ This should let you enter your Zimbra account.
Finally, the right URL for the zimbraWebClientLoginURL is '../service/spnego' (not '../../service/spnego').
Last but not least, when enabling the DEBUG traces, the documentation states you need to *ADD* '-DDEBUG=true -Dsun.security.spnego.debug=all' and other stuff to the existing setting, not replace.
By replacing it, you remove the configuration settings for Kerberos and this creates other problems :)
any resolution? i can't get SSO/spnego working either. Followed the Appendix in the Admin Manual word for word, but no luck.
