Hello Markus
Thank you very much, everything works now. Only two question left
1) Is it necessary to run commands specified below every 30 day?
msktutil --auto-update --verbose --computer-name proxy1-k
msktutil --auto-update --verbose --computer-name proxy2-k
msktutil --auto-update --verbose --computer-name proxy-k
As I understand I should run them on one proxy1 and then copy updated
keytab file to proxy2 every month.
2) Can I use kerberos somehow to authenticate skype? All internet
browsers work but skype doesn't, only works by specifying user/pass in
configuration and as I think it uses basic ldap auth.
When there was NTLM auth, it worked, but now I removed all NTLM from
squid, only kerberos negotiate and basic is left.
