glibc contains two versions of finction stpncpy
sh-4.2$ nm --dynamic --defined-only /lib64/libc.so.6 | grep stpncpy
0000003ce1c89b00 i stpncpy
0000003ce1c89b00 i __stpncpy
0000003ce1d040a0 T __stpncpy_chk
We should use more portable version of stpncpy without prefix with underscores.
The function __stpncpy was used in initial veersion

The size of output buffer(obufsize) was longer than initialised data.
In calculation, uint32_t was used for length of the cryptotext,
but uint16_t was written into buffer. The end of buffer was not initialised
and it caused valgrind warning.
Use of uninitialised value of size 8

Use a script to update DEBUG macro invocations to use it as a variadic
macro, supplying format string and its arguments directly, instead of
wrapping them in parens.
This script was used to update the code:
grep -rwl --include '*.[hc]' DEBUG . |
while read f; do
mv "$f"{,.orig}
perl -e \
'use strict;
use File::Slurp;
my $text=read_file(\*STDIN);
$text=~s#(\bDEBUG\s*\([^(]+)\((.*?)\)\s*\)\s*;#$1$2);#gs;
print $text;' < "$f.orig" > "$f"
rm "$f.orig"
done

Declarations of public functions was in header files,
but header files was not included in implementation file.

Some platform have header file endian.h and anothers have sys/endian.h.
We nedd to use conditional build to handle it correctly, therefore new header
file sss_endian.h was created.

Implemented working versions of the following functions for libcrypto:
sss_base64_encode
sss_base64_decode
sss_hmac_sha1
sss_password_encrypt
sss_password_decrypt
test_encrypt_decrypt now expects EOK from libcrypto.
test_hmac_sha1 now expects EOK from libcrypto.
Added test_base64_encode to test base64 encoding implementation.
Added test_base64_decode to test base64 decoding implementation.

extract the cleartext password back.
So far, only NSS-based implementation is provided.

supported by SSSD.
