There is a NUL (\x0) character at the end of LDAP error messages that are logged by PSPNG. (Well... I did mistakes 
)
Here is a sample of these messages, selected from the output of
cat -v grouper_error.log* | grep -B1 '\^@' |
(NUL appears as "^@")

It is not proper to have non printable characters in a log file.
In particular it can cause problems with some tools used to inspect these logs, e.g. if one forgets to add the "-a" option to a "grep" command, the result will be incomplete.
The root cause is probably in the ldaptive library, but nevertheless PSPNG could filter out such spurious NUL character.
Minor, but easy to fix.
