RE: Patch to log failed simple binds (ITS#1809)
The syslog feature itself is system-dependent, so your patch needs to be
conditionalized. Surrounding it with #ifdef LDAP_SYSLOG might be a good
Also, the Debug macro currently invokes syslog automatically if so
so your patch may be better as a Debug invocation. (But in that case, you
can't control the syslog level directly so that may not be the best approach
after all.) The NEW_LOGGING facility provides more control, but is not yet
ready for prime time...
