Checkmk Werk 13606: Simplify adding CAs and new permission to perform requests from the Checkmk server

by Tom Baerwinkel

ID: 13606 Title: Simplify adding CAs and new permission to perform requests from the Checkmk server Component: Multisite Level: 1 Class: New feature Version: 2.1.0i1 With the new option "Fetch certificate from server" in the global settings "Trusted certificate authorities for SSL" and "Connection to remote agent bakery" it is now possible to contact a host from the Checkmk server to retrieve CA information. To perform these actions a user needs the permission "Perform requests from the Checkmk server". By default only the Role admin has this permission. The mechanism to fetch the data is essentially the same as for the "Livestatus encryption of host HOSTNAME" in the "Distributed monitoring".

Checkmk Werk 13507: Fix simulation mode in service discovery and connection tests

by Ronny Bruska

ID: 13507 Title: Fix simulation mode in service discovery and connection tests Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 Werk #13505 fixed the simulation mode for already existing hosts with existing cache. If a host has no cache, like new added hosts, the "Check_MK Discovery" service will now show an informational output "Got no data (Simulation mode enabled and no cachefile present)", like in previous 1.6 versions. Furthermore, no service discovery will be processed. While executing connection tests in simulation mode, the "Agent" section will use the cache file, if present, or is showing the above mentioned message. The SNMP datasources will not be contacted any more if simulation mode is enabled.

Checkmk Werk 13508: Fix failed logins for LDAP user created with Checkmk versions below 1.4

by Ronny Bruska

ID: 13508 Title: Fix failed logins for LDAP user created with Checkmk versions below 1.4 Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 Since werk #13501, only LDAP connections are processed, the user has the user attribute for. In older versions of Checkmk only one LDAP connection was supported, setting the user attribute "connector" to "ldap". This attribute was later changed from "ldap" to "default", leading to failed logins now, because no LDAP connection matches. The problem will be fixed with this werk. A workaround was, to manually change the user attribute of affected users from 'connector':'ldap' to 'connector':'default' in ~/var/check_mk/USERNAME/cached_profile.mk.

Checkmk Werk 13323: Fix validation of host addresses in different situations

by Lars Michelsen

ID: 13323 Title: Fix validation of host addresses in different situations Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 There are different situations where host addresses can be configured within the Checkmk setup (e.g. Additional IP addresses, host diagnostic, management address). In some of them host names, IPv4 and IPv6 addresses are allowed and in some of them only a subset. Depending on the situation, the validation should be as specific as possible, but the inserted value was not correctly validated in all the situations.
