Error when querying Active Directory using ldapsearch

Hi there,

I encountered the following error when trying to query AD using ldapsearch.

ldap_search: errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0

The ldapsearch returned some results before throwing the above error.


The following is exactly what I did:


ldapsearch -h abccorp.sales.local -p 389 -b "dc=sales,dc=local" -D acme_admin -w passw0rd  -s sub "givenName=mark*"  "givenname"


CN=Mark NG,OU=Marketing & Sales,DC=Sales,DC=local
givenName=mark

CN=Sue Jones,OU=Marketing & Sales,DC=Sales,DC=local
givenName=sue

ldap_search: resultCode 1 (Operations error)
ldap_search: errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0



If I modify the base parameter in the ldapsearch, I get search results without an error. Look at the "-b" parameter.


ldapsearch -h abccorp.sales.local -p 389 -b "ou=SM Group,dc=sales,dc=local" -D acme_admin -w passw0rd  -s sub "givenName=mark*"  "givenname"


CN=Mark NG,OU=Marketing & Sales,DC=Sales,DC=local
givenName=mark

CN=Sue Jones,OU=Marketing & Sales,DC=Sales,DC=local
givenName=sue



Any help is appreciated.

Regards.
