Is it possible to set 'Skip Group Modifications' on a already installed environment

[#1]

Our environment is already installed. Now we want to use an LDAP for the user managment (hdfs, oozie, sqoop, etc...). When starting the hosts an error is raised about usermod is not possible ( user does not exist in /etc/passwd).

During installation you can set 'Skip Group Modifications'. How can this be set afterwards?

You could try setting this cluster-env parameter "ignore_groupsusers_create" using configs.sh.

cd /var/lib/ambari-server/resources/scripts

./configs.sh set $AMBARI-SERVER-FQDN $AMBARI-CLUSTER-NAME global ignore_groupsusers_create "true"

Hope this helps.

This works after replacing "global" with "cluster-env", and quotes on the new value are not required, for example:

./configs.sh set h10.example.com c1 cluster-env ignore_groupsusers_create true

Thanks for the response. I've tried it but get an error.

@Mart van Loon

Instead of global could you try "cluster-env" ?

I've made a script which does the config.sh set for all configs (see attachement). This works.
