We should be good for the size:
MAX_AUTHID_AS_STRING_LEN is the size for userAsInt converted to a string,
MAX_USERNAME_LEN is the username length, and the remaining should cover commas
and authorization state.
and 2 it the length of authorization state.
plus all the commas
we should be good for the size
