ldapsearch with GSS-SPNEGO

[Cai Fa]

Hi All,
I try to do ldapsearch an Active Directory by GSS-SPNEGO.
> ldapsearch -Y GSS-SPNEGO -LLL -s "base" -b "" supportedSASLMechanisms -h 10.155.60.241 -v

But I got following error:
ldap_initialize( ldap://10.155.60.241 )
SASL/GSS-SPNEGO authentication started
ldap_sasl_interactive_bind_s: More results to return (-15)

It looks like there are some SASL steps need to do, but the client
return an error.

Is there anyone can help me?
Thanks.
