SSO locked me out of Discourse!

[TwelveMonkeys]

I’m trying out SSO for my Wordpress site and it seems that if you get the configuration wrong, you can get locked out of your admin account.

Unfortunately, I am but a lowly publisher/admin. So the instructions here Sign In Error (SSO may be enabled) are no use to me. I am only vaguely technical - I paid a developer to set up Discourse on Digital Ocean for me.

I know what SSH is, but I haven’t touched a command line for several years. I either need some real layman step-by-step instructions, or I’ll have to pay another third party to sort this out.

Thanks in advance.

What if you check it by mistake?

If you check enable_sso by mistake and need to revert to the original state and no longer have access to the admin panel

run:

./launcher enter app
rails c
irb > SiteSetting.enable_sso = false
irb > exit
exit

Thanks for the swift reply, but as I said, I paid a developer to set this up.

What I need are step-by-step instructions for Digital Ocean - where do I run these commands?

Sorry for being a newbie, but I’m evaluating Discourse and need to find out if I can administrate this forum myself or whether I need to pay someone to take care of the server side of things.

Thanks.

Do you know how to login to your Digital Ocean VPS using a SSH client ?

[TwelveMonkeys]

I’ve never done it before on Digital Ocean, but I’m sure I could work it out. Can I use the Terminal on my MacBook?

If so what info will I need to run the commands above?

Many thanks

[thangngoc89]

Yes. You can use Terminal on MacBook to login via ssh to your VPS.
After login to your VPS. run these command

# cd /var/discourse
# ./launcher enter app
$ rails c
[1] pry(main)> SiteSetting.enable_sso = false
[2] pry(main)> exit
$ exit

[TwelveMonkeys]

thanks very much!

However I managed to reset the forum without having to open a command line.

By typing in the IP address, not domain name of my forum I was able to login and uncheck the SSO settings .

Now the forum is back up and running. Many thanks for your assistance!

How did you even install Discourse without ever connecting to the server before?

Anyway: Your mac ships with Terminal which lets you connect to the server too. Open it and type ssh <yourserver_IP_or_domain> and you will be able to log in as long as you didn’t use some private key when setting up the server.

[TwelveMonkeys]

Thank you for the advice.

FYI I’m a publisher, I don’t have a background in server administration - somebody else set the forum up for me.

Whilst I’m pretty technical, I need to feel confident that I can’t ‘break’ the installation purely by changing some settings in the admin panel.

This to me is a test as to whether Discourse will work for me and hence be adopted by the masses -like where Wordpress is at now.

[Moter8]

Oh I see, that’s fine too, Discourse Is fairly easy to administer for non-technical people too.

Back to Topic: the “Enable SSO” Option should have some sort of warning (Don’t enable this unless you know what it is for)

[codinghorror]

Good point I added this to the end of the site setting description for enable_sso

(WARNING: can prevent anyone from logging in if not properly configured when enabled; also disables invites)

[kpfleming]

This is a configuration bug that you’ll probably want to get corrected, otherwise your users will also be able to bypass your SSO.

[TwelveMonkeys]

Thanks for the advice but I’m skipping SSO for the moment.

Too complicated to set up for non sysadmin types like me.

There is a Wordpress plugin for this

WP Discourse SSO Plugin

Piggybacking off the magnificent work of @AdamCapriola and @ArmedGuy, I’ve cleaned up and refactored the code into a WordPress plugin to normalize the setup procedure. I want a few more people to test it before I submit it to the public repo. I’ve created a composer project out of it, however, so you should be able to install it as a wp dependency easily by using a stack like Bedrock. Setup is simple: Install the plugin. Generate a random string to use as the secret key. Copy this secret k…

[TwelveMonkeys]

Thanks, yes I have the Wordpress plugin installed - it’s pretty intuitive, however I’m struggling with the Discourse settings, in particular the following:

I have set the secret key, but I have no idea what the SSO url is and the implications of the override settings.

Many thanks for your help and encouragement.

Finally managed to get SSO working!

[TwelveMonkeys]

Thanks, I got this work finally. It seems that my server works a little differently. Being a newb, I thought it might help others with the same issue:

the irb command was giving me errors

NameError: undefined local variable or method `irb’ for main:Object

Instead I was getting this prompt after ‘rails c’

1] pry(main)>

This might as well have been in Sanskrit, but a little Googling told me this was an alternate to irb so I just entered the command:

SiteSetting.enable_sso = false
exit

And that seemed to work.

Thanks again!

Fixed the instructions for future travelers.

[Rafiki]

Appreciate help guys. Have ssh into my bitnami discourse stack and can’t get the commands to work. When I run rails C I get this error before I even get to running the = false command.

Looks like your app’s ./bin/rails is a stub that was generated by Bundler.

In Rails 4, your app’s bin/ directory contains executables that are versioned
like any other source code, rather than stubs that are generated on demand.

Here’s how to upgrade:

bundle config --delete bin # Turn off Bundler’s stub generator
rake rails:update:bin # Use the new Rails 4 executables
git add bin # Add bin/ to source control

You may need to remove bin/ from your .gitignore as well.

Any advice appreciate as need to get the SSO turned off asap. Thanks!
