Hey Clyde! Good to hear from you. We use the [Etc module that likely makes sys calls](https://ruby-doc.org/stdlib-2.6.3/libdoc/etc/rdoc/Etc.html#method-c-getgrgid). Which is to say, it likely relies on your LDAP. It’s probably functionally equivalent to the `groups` command or `id`, how those commands get populated. In fact this issue is coming from an initializer in a configured file: `/var/www/ood/apps/sys/dashboard/config/initializers/ood.rb`. We’re adding file browser dropdowns based off of the group id. If this isn’t nessicary, or you don’t have or want those dropdowns, then you can safely remove that portion. It’s purely addititve so it’s safe to remove. Though we rely on userids and group ids in all sorts of places, so even if you don’t need that portion, or that feature, you may run into similar errors. You can provide the whole file here and we can sort out what you’d want to keep and what you can throw away. ---

Thanks Jeff We are using groups for access to some portions, I want to not have the app crash if it encounters an error on retrieving groups. We have v1.35.3 ```auto # /etc/ood/config/apps/dashboard/initializers/ood.rb OodFilesApp.candidate_favorite_paths.tap do |paths| # add project space directories projects = User.new.groups.map(&:name).grep(/^P./) paths.concat projects.map { |p| Pathname.new("/fs/project/#{p}") } # add scratch space directories paths << Pathname.new("/work") paths << Pathname.new("/scratch") end # only show develop dropdown to users in group 'RSI-A-EC-HubDeveloper' Configuration.app_development_enabled = OodSupport::Process.groups.include?( OodSupport::Group.new("RSI-A-EC-HubDeveloper") ) ``` ---

This should work for you, to catch the exception. ```ruby # /etc/ood/config/apps/dashboard/initializers/ood.rb OodFilesApp.candidate_favorite_paths.tap do |paths| # add project space directories projects = User.new.groups.map(&:name).grep(/^P./) paths.concat projects.map { |p| Pathname.new("/fs/project/#{p}") } # add scratch space directories paths << Pathname.new("/work") paths << Pathname.new("/scratch") end dev_enabled = false begin # only show develop dropdown to users in group 'RSI-A-EC-HubDeveloper' # and catch the error if you can't determine the group dev_enabled = OodSupport::Process.groups.include?( OodSupport::Group.new("RSI-A-EC-HubDeveloper") ) rescue => e Rails.logger.error "Can't determine developer group memebership because #{e.message}" end Configuration.app_development_enabled = dev_enabled ``` To the actual error though, `100187` looks like a subgid, is that right? Is this in a rootless container? OOD takes id/gids from the process. I guess it got the subgid from the host when it should have gotten what it was mapped to in the container? ---

We’re using SSSD to pull groups from an active directory server. This is not in a container, but the global GID’s change frequently and we run into errors when the AD servers are not yet synchronized. I’ll give this a try and report back ---

Hey, hope this worked out for you. I’m solving it with the response above, but just let us know if you run into more issues or have other questions! ---
