[//]: # (werk v2) # ldap: you can't create a new connection with an existing suffix key | value ---------- | --- date | 2024-09-12T05:38:52+00:00 version | 2.4.0b1 class | fix edition | cre component | rest-api level | 1 compatible | no Via the REST-API is was previously possible to create more than one ldap connection that had the same suffix. This was incorrect and doesn't match the behaviour of the UI. This werk addresses this issue by no longer allowing the same suffix on more than one ldap connection.
