My testing shows a leak in ldap_sasl_interactive_bind_s().  I tried to chase the
leak with fnccheck, but after compiling both openldap and my testing program for
profiling, fncdump dumps itself.  Anyway, ldap_sasl_interactive_bind_s() frees
SASL_INTERACT prompt result, but I do not think it frees other prompt buffers. 
I looked throught sources for ldapsearch and slurpd, but I did not find ways to
free the buffers allocated in _ldap_interact.

Somewhat related issue I have is that the following pseudo code does not work. 
The ldap connection needs to be reset after each ldap_sasl_interactive_bind_s. 
I am not sure if this behaviour is by design, but I was hoping that it'll work
just like it does with simple bind.

ldap_initialize
while
   get auth input
   ldap_sasl_interactive_bind_s(authcid,authzid,mech,pass...)
endwhile

Thanks
