External Access to LDAP

Hi everyone
we are trying to integrate the authentication of our GOGS Server with UCS Server throw LDAP
but if I try:

ldapsearch -x -D cn=gogs1,cn=memberserver,cn=computers,dc=domain,dc=es -W -h ucs.domain.es -p 7389 uid=Administrator

i receive no response:

Enter LDAP Password: 
# extended LDIF
# LDAPv3
# base <> (default) with scope subtree
# filter: uid=Administrator
# requesting: ALL

# search result
search: 2
result: 32 No such object

# numResponses: 1

So I’m capable to reach and log in the ldap server but i didn’t see any data.
Differently if i try the same command on the UCS shell i receive the data of the administrator

Can anyone help?
