Valgrind reporting an invalid file descriptor
I'm writing an program with LDAP but probably something goes wrong
when I try to shutdown the connection.
First I call ldap_initialize, after that I call a bind operation.
(Using function ldap_bind_ext) That goes all very well.
Then I try to close the connection with ldap_unbind_ext. This goes
according to the return value ok, but when running in valgrind I see a
Warning: invalid file descriptor -1 in syscall close()
==4733== Warning: invalid file descriptor -1 in syscall close()

==4733== by 0x804A167: main (ldap.cpp:283)
Is this a bug in the LDAP library, or did I forgot a call to
something ? According to the documentation (man 3 ldap_unbind_ext) is
this the only call I need to do.
Can somebody enlighten me here ?
