Yes, although AD-SIGNTICKET might be the correct name now that I look
(the constants in the code are a little confusing; the data structure is
called krb5_ad_signedpath and the key usage constant is similar, but the
authdata constant is KRB5_AUTHDATA_SIGNTICKET).

The integer at offset 155 stands for AD-IF-RELEVANT; the integer at
offset 6 of the AD-IF-RELEVANT blob stands for AD-SIGNTICKET; and the
blob itself is an enctype (aes256-cts) and a checksum of cksumtype
hmac-sha1-aes256.
