According to thist data
https://cwiki.apache.org/confluence/display/DIRxPMGT/Kerberos+EncryptedData
http://tools.ietf.org/html/rfc3961

encryption type 5 is DES3_CBC_MD5
encryption type 7 is DES3_CBC_SHA1

but the file  wireshark/epan/dissectors/packet-kerberos.c
#define KRB5_ENCTYPE_DES3_CBC_SHA                  5
#define KRB5_ENCTYPE_DES_HMAC_SHA1                 8

Currently, my network enviroment only has DES3_CBC_MD5, the attached picture
shows that the type value is correct, but wrong string.
For the other types, I don't have the enviroment for testing, and some types
can not find the reference
