(Im with jneves)
Ok some more information...
When I try to login I get the following message:
pam_ldap: error trying to bind as user "uid=marco.silva,ou=Users,dc=servidor,dc=eb23,dc=net" (Invalid credentials)
In ldap.secret I have the secret that is available at the "LDAP info" section in ebox.
rootbinddn is commented out, what is the "cn" I should use? admin? ebox?
