Solution

  1. While logged in as the site user, run a find command to search for that particular user

    OMD[mysite]~$ find . -name "my_ldap_user (T0)_sync_time.mk" ./var/check_mk/web/my_ldap_user (T0)_sync_time.mk

    This command found a filename related to that user within ~/var/check_mk/web/

  2. Move that file outside of your site folder

    OMD[mysite]~$ mv ~/var/check_mk/web/my_ldap_user (T0)_sync_time.mk /home/mylinuxuser/

    In the above example, the file was moved to the home directory of a basic Linux user
    .

  3. Verify the configuration

    OMD[mysite]~$ cmk-update-config -vv
