Kerberos Troubleshooting Section says encryption types supported are:
DES_CBC_MD5,DES_CBC_CRC,and DES_CBC_MD4

This is incorrect.

Earlier in J2SE 1.4.2 we had support for des-cbc-md5 and des-cbc-crc.
We never had support for dec-cbc-md4. Starting from J2SE 1.5.0 we now
have support for triple DES.

Hence this list should be updated to:
des-cbc-md5, des-cbc-crc, des3-cbc-sha1
