Not only check if it exists and is executable, but also
check whether it accepts the command line "krb5-config --libs gssapi".

failing on a Solaris machine due to krb5-config raising errors on

entry->num_of_strings is a uint16_t. Casting it with
(int *)&entry->num_of_strings
is wrong, because it gives add_string_to_array the illusion that the object
"num" points to is an int, which it is not.
In case we are running on a machine where "int" is 32 or 64 bits long, what
happens with that cast? "add_string_to_array" interprets the byte field that
starts where "num_of_strings" starts as an int. Under very particular
circumstances this might work in a limited number of cases: When the byte order
of an int is such that the lower order bits of the int are stored first, the
subsequent bytes which do not belong to the uint16_t anymore happen to be 0 and
the result of the increment still fits into the first 2 bytes of that int, i.e.
the result is < 65536.
The correct solution to this problem is to use the implicit type conversion
that happens when an assignment is done.
BTW, this bug is found if you compile with -O3 -Wall, it shows up as a warning:
rpc_server/srv_eventlog_lib.c:574: warning: dereferencing type-punned pointer
will break strict-aliasing rules

When set to yes, "force username map" forces every user, even AD
users, through an NSS lookup. This allows the token to be overridden
with information from NSS in certain broken environments.
Windows 7 looks at the negotiate_flags
returned in this structure *even if the
call fails with access denied ! So in order
to allow Win7 to connect to a Samba NT style
PDC we set the flags before we know if it's
an error or not.
