The following gotchas often catch people out. Kerberos is case sensitive. Your realm must
be in UPPERCASE, or you will get an error: <quote>Cannot find KDC for requested realm while getting
initial credentials</quote>. Kerberos is picky about time synchronization. The time
- according to your participating servers must be within 5 minutes or you get an error
+ according to your participating servers must be within 5 minutes or you get an error:
<quote>kinit(v5): Clock skew too great while getting initial credentials</quote>.
Clock skew limits are, in fact, configurable in the Kerberos protocols (the default is
5 minutes). A better solution is to implement NTP throughout your server network.
Kerberos needs to be able to do a reverse DNS lookup on the IP address of your KDC.
Also, the name that this reverse lookup maps to must either be the NetBIOS name of
- the KDC (i.e., the hostname with no domain attached), or it can alternately be the
+ the KDC (i.e., the hostname with no domain attached) or the
NetBIOS name followed by the realm. If all else fails, you can add a
<filename>/etc/hosts</filename> entry mapping the IP address of your KDC to its
NetBIOS name. If Kerberos cannot do this reverse lookup, you will get a local error
when you try to join the realm.
