Hello, I've installed a samba4 server and now I've tried to get a kerberos ticket, like this: base:/usr/local/samba# kinit stefan stefan@SAMBA4.LOCAL's Password: kinit: converting creds: Invalid argument I'm using heimdal-clients (0.6.3) and samba4 svn r22508. My krb5.conf test configuration: [libdefaults] default_realm = SAMBA4.LOCAL kdc_timesync = 1 ccache_type = 4 forwardable = true proxiable = true [realms] SAMBA4.LOCAL = { kdc = base.samba4.local admin_server = base.samba4.local } If I start samba with "-i -d 2" I got this log: ...
