    Unable to authenticate, please check your API credentials (RestApiClient.php:182)

    New installation without Master Setup (icinga2 node wizard /no )
    • Icinga2 new installation
    • Master Zone added
    • icinga2 api setup
    • comment out /* Include conf.d in icinga2.conf */

    What is the diffenrent between /etc/icinga2/conf.d/api-users.conf and /etc/icinga2/features-available/api.conf ?

    I though from version 2.8 conf.d will not be used anymore (buttom up)

    • [root@mon conf.d]# icinga2 api setup

    information/cli: Generating new CA.

    Now restart your Icinga 2 daemon to finish the installation!

    What is the diffenrent between /etc/icinga2/conf.d/api-users.conf and /etc/icinga2/features-available/api.conf ?

    api.conf is for configuring your api. conf.d/api-users.conf is the default/example place to configure your api-users.

    Where do you have this, and is this the user you have configured for your director ?:


    I though from version 2.8 conf.d will not be used anymore (buttom up)

    conf.d has nothing to do with buttom-up. Its the default/example path for local configuration files, like the api-users.

  • hi

    the ApiUser "root" is located under /etc/icinga2/conf.d after icinga2 api setup

    ist it possible to test with curl command directly to the api on endpoints ?

    i saw some of the other posted used "director" instead of root ,did i missed any thing in config

  • comment out /* Include conf.d in icinga2.conf */

    the ApiUser "root" is located under /etc/icinga2/conf.d

    I just want to be sure: If you say "comment out" you mean you removed the "/*" and the "*/" or you inserted it ?

    1. icinga2 object list --type=ApiUser #gives you all configured api users
  • You can configure the ApiUser anywhere you want, just ensure it is a local secure location which is included by icinga2.conf

    If you want to test the REST API, start reading the corresponding chapter inside the Icinga 2 docs. Everything you need is explained with examples there. Hint aside: The Director uses config packages for deployment, but also other things.

  • hi,

    i removed the comment on icinga2.conf

    include_recursive "conf.d"

    used the root / pass in /etc/icinga2/conf.d/api-users.conf


    icinga2 daemon -C

    systemctl restart icinga2

    still Error 182

    Reboot Icinga2 Master

    worked great no more API 182 error and Director can import database .

    many thanks !
