Kerberos error - errortype 
Explanation
This message is issued to syslog when the orshd server detects
an error in the Kerberos communication with the client.   

errortype can be one of the following: 
V1 validation
In the Kerberos exchange between client and server, the V1 validation
failed.
V2 validation
In the Kerberos exchange between client and server, the V2 validation
failed.
AP REQ validation
In the Kerberos exchange between client and server, the AP REQ
validation failed.
checksum failed
The orshd server start up configuration options specify that
the Kerberos checksum must be valid  (using -m option). In the Kerberos
exchange between client and server, the checksum was not valid.
encryption required
The orshd server start up configuration options specify that
kerberos and encryption will be used (using -e option). In the exchange
between client and server, the client did not specify encryption.
forwarding is unsupported
Credentials forwarding was requested by
the orsh Kerberos client.  The orshd server does not support credentials
forwarding.

System action
orshd ends.

Operator response
Contact the system  or  network administrator.

System programmer response
Turn on debugging for orshd to determine where in the Kerberos
flow  the error occurred.  Verify that the orsh client is a valid
Kerberos V5 client.  There is probably a mismatch in the Kerberos
support or options supported between the orsh client and server. 
Review the Kerberos configuration between the client and the server.
