Re: ldap user with starcluster

Hi,

I tried adding regular user (not LDAP).
I follow http://web.mit.edu/Star/cluster/docs/latest/plugins/users.html
I start the cluster after I add to the config file the lines:

plugins = create users

[plugin createusers]
setup_class = starcluster.plugins.users.CreateUsers
usernames = ralph, julia, richard

It create the users on the master and on node.
First I couldn’t login from master to node with no password and suddenly start working.
But major problem, it did not build the /opt/sge6 (which needed for submitting jobs) as it did before adding the above lines.

What can cause the problem? Where can I find error log for tracking the problem?

Thanks,
Shlomit.

So Shlomit,

It seems like you are trying to do something special. And I cannot help you much.

However, I vaguely recall someone on this list trying to run starcluster with many users. If you have time, you may wish to look at the archives - yet this may be a wild goose chase since I do not recall LDAP being brought up.

If you do solve the problem, please send the solution to the list - so we will all have it.

Hi,

User sgeadmin define as CLUSTER_USER. With sgeadmin I can login from master to node without password.
Did not use plugins or special AMI.

Hi Shlomit,

When you configured the cluster to start, did you define the user?

Can you just SSH the master without a specific user?

Some plugins define users for you, did you use one?

Also, did you use a special AMI configured a certain way?

Hopefully with some more information it will be possible to figure out what is going on.

Hi,

1. I successfully login to cluster with the command:
         starcluster sshmaster -u username physicscluster
    if username is local user but not with ldap user.
    I get the error:
    Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
    How can I login to the cluster with the above command as ldap user?

2. How to allow/configure ldap user to submit/run jobs on the cluster? any documentation?.

Thanks.
