[pubcookie-dev] can't increase username lenght in pubcookie code :-(

[Jim Fox]

We've never used any value but 42, but it ought to be able to
change.  Make sure you do a complete rebuild of both the
login server and the module with the new value of PBC_USER_LEN
and PBC_TOT_COOKIE_DATA.  ("make clean", and "make", and "make install").
