Title: LDAP connection ids that are invalid user ids will no longer crash Checkmk
Component: Setup
Level: 1
Class: Bug fix
Version: 2.3.0b1
LDAP connection names have the same requirements as user ids and
Checkmk version 2.2.0 introduced stricter requirements for them.
Up until now, Checkmk did not check these requirements when creating new LDAP
connections nor did an update convert them to fit the new requirements.
This Werk tightens LDAP connection id validation to fit the new requirements.
Updating Checkmk will cause all spaces in connection ids to be replaced with
underscores, as this is the most common manifestation of this incompetability.
If you still are unable to update, please check if your connection id consist only
of letters, digits, dollar, underscore, dash, dot, and at and starts
with a letter, digit, dollar, or underscore. If not, rename your connection id
before updating.
