I upload the ldif file below into my openldap server:

dn: dc=ufv,dc=br dc: ufv objectclass: dcobject objectclass: organization o: Universidade Federal de Vicosa

dn: ou=group,dc=ufv,dc=br ou: group objectclass: top objectclass: organizationalunit

But when i try the command below, i get invalid credential

sioux@gustav$ ldapsearch -x -W -D 'uid=sioux,ou=people,dc=ufv,dc=br' -b dc=ufv,dc=br Enter LDAP Password: ldap_bind: Invalid credentials (49) sioux@gustav$

And when i try:

$ ldapsearch -Y GSSAPI -b dc=ufv,dc=br

it works perfectly.

Any ideia about why it does not work ?
