Security Software

hi, i try to connect ldap server with the conections are encripted from server side; so i create my own CA and a server ceritificate trusted by this CA using certutil and do this:
1) create a CA data base
2) create a CA certificate and sotore them in CA database
3) add this certificate to directory server certificate database
4) create a request of a server certificate
5) sign this request
6) add the trusted server certificate to directory server certificate database

# .../shared/bin/certutil certutil -V -u V -n einstein.prueba.uy -d .../alias -P slapd-einstein-
certutil: certificate is valid

# .../shared/bin/certutil -L -d .../alias -P "slapd-einstein-"
ca-cert CT,,
einstein.prueba.uy CTu,Cu,Cu

but when i try to search, i have the followin message:

# ldapsearch -x -v -Z -p 389 -h 100.0.4.180 -D "cn=bindmailUsers,cn=mailUsers,dc=prueba,dc=uy" -w passbindmailUsers -b "cn=mailUsers,dc=prueba,dc=uy" "uid=*" -d -1
....
