[Samba] error, when searching in AD database

[Norbert Wegener]

I have joined a windows domain, which is part of a larger active 
directory forest.
wbinfo -m gives me a long list of domains.
ldapsearch gives me a long list of AD information, but in the end an error:

 ldapsearch -LLL -C -h ww901.mycompany.net  -b 
"DC=WW901,dc=mycompany,dc=NET" -s sub 
"(&(servicePrincipalName="host/*")(objectclass=computer)) "

But in the end I get:
Operations error (1)^M
Additional information: 00000000: LdapErr: DSID-0C090627, comment: In 
order to perform this operation a successful bind must be completed on

What does this error mean? I got lots of information from AD And should 
have authenticated, correct??

Thanks
