Config insertion LDAP errors from setup are not shown

Description

When the insertion of the configuration object in the LDAP server fails, no error is shown to the user. This is because the setup code was not adapted to changes #4893 (closed)

FusionDirectory Version

Since 1.1

Steps to Reproduce

1. Go through the setup to the configuration step
2. Break your LDAP server or stop it
3. Save the configuration

Expected behavior:

Have an error on-screen

Actual behavior:

Fails silently and goes to the next step

Additional Information

You may have errors from other operations when trying to reproduce, but not the one from the actual configuration save.
