Error trying to add "Auxiliary Class Assignments" on LDAP Schema Extensions

Hello, I get an error when I try to add "Auxiliary class assignments" on LDAP schema extensions in version 9.2.*

this is the error message:

[2417001] Unable to setup wizard page (Connector schema configuration).
at VI.FormBase.UILogic.TriggeredExecution._EventHandler(Object sender, EventArgs e)
at VI.UI.Wizards.Wizard.Next()
at VI.UI.Wizards.WizardPage.Setup(WizardPageSetupArgsEx args)

at VI.Projector.LDAP.Driver.LdapComponentDescriptor`1.GetConnectionString()
at VI.Projector.LDAP.Driver.LdapComponentDescriptor`1.GetConnectionString()

I get this error message when I try to add something into this assignments or even if I just add it and then try to click on Next. So either way, it doesnt work.

You guys know any solution to this?

PS. I've finished the synchronization object all the way and I have contact with the server (LDAP) and get data out of it. So there is no problem with the connection to the server, just adding this Auxiliary class assignments in the configuration.
