Jellyfin User Permission Issues — Complete Guide

In this tutorial, you'll learn about Jellyfin User Permission Issues. We cover key concepts, practical examples, and best practices.

Hook

You add a new user in Jellyfin and grant them access to the Movies library. They log in and see "No items to display." You check the library access — it is enabled. You remove and re-add the user — same empty screen.

The Wrong Way

Granting a user access to every library and enabling all permissions at once can hide which specific setting blocks access. It also exposes libraries you may want private.

// BAD: Granting all permissions to test
{
  "EnableAllChannels": true,
  "EnableAllFolders": true,
  "EnableAllDevices": true,
  "EnableLiveTvAccess": true
}

User sees all libraries — including private admin content
Still: "No items to display" for Movies

The blanket fix does not reveal the actual blocker, and it over-exposes content.

The Right Way

Step through the permission chain methodically.

# 1. Check user policy via API
curl -s -H "X-Emby-Token: <api-key>" \
  "http://localhost:8096/Users/<user-id>/Policy" | jq .

{
  "IsAdministrator": false,
  "EnableContentDeletion": false,
  "EnableMediaConversion": false,
  "BlockedTags": ["xxx"],
  "MaxParentalRating": 99
}

The BlockedTags or MaxParentalRating may be filtering all content. In Jellyfin Dashboard → Users → select user → Parental Control:

• Set Max Parental Rating to Unrated.
• Clear all Blocked Tags.

# 2. Verify library access
curl -s -H "X-Emby-Token: <api-key>" \
  "http://localhost:8096/Users/<user-id>/Items?IncludeItemTypes=Movie&Recursive=true" | jq '.TotalRecordCount'

0

If blocked tags and ratings are clear but items still show 0, the user may not have access to the media folder itself. Check folder permissions on disk:

ls -ld /mnt/media/Movies/
# Must be readable by the jellyfin user

Prevention

• Set library access first, then fine-tune permissions.
• Use Jellyfin's built-in Access Schedules for time-based restrictions.
• Apply parental rating tags consistently in your metadata.
• Create separate users for different access levels (kids, adults, guests).
• Test new user permissions by logging in as that user in an incognito window.

Advanced Troubleshooting

Check the Logs

Most TOOL errors are logged to stdout or a dedicated log file. Check your logs first:

# Check system logs
journalctl -u tool --since "1 hour ago"

# Or check the application log
tail -50 ~/.tool/logs/error.log

Test with a Minimal Example

Create the simplest possible tool configuration to verify the base setup works:

tool --version
tool --help

If the minimal test passes, add configuration options one at a time until you find the breaking change.

Common Configuration Mistakes

• Using the wrong file path or URL in configuration
• Forgetting to restart TOOL after changing config files
• Mixing tabs and spaces in YAML configuration files
• Setting incorrect permissions on configuration directories

When to Reinstall

If none of the above resolves the issue, consider a clean reinstall:

# Backup your configuration
cp -r ~/.tool ~/.tool.bak

# Remove and reinstall
# Follow the official TOOL installation guide

This ensures you start from a known good state and can isolate the issue.

Common Mistakes with user permission

1. Misunderstanding that String is [Char] with poor performance for large text operations
2. Using foldl instead of foldl' causing stack overflow on large lists
3. Forgetting deriving (Show, Eq) on custom data types needed for debugging

These mistakes appear frequently in real-world JELLYFIN code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
