How To Fix Login Issues with Newly Created User Account on Ubuntu

Ubuntu 15

Creating a new user account on Ubuntu can sometimes result in login issues. This article will guide you through the steps to troubleshoot and fix these issues. We will cover checking the home directory configuration, verifying directory permissions and ownership, ensuring other users don’t have blanket write access, setting the user’s primary group, and adding the user to additional groups or making them an administrator.

Checking the Home Directory Configuration

The first step in troubleshooting login issues is to check the home directory configuration for the user account. This can be done by running the command grep username /etc/passwd in the terminal. Replace “username” with the actual username of the account you’re troubleshooting.

This command will display the home directory configured for the user account. If the home directory listed is different from the one you created manually, you can change it using the command sudo usermod -d /home/username username. The -d parameter specifies the new home directory for the user.

Verifying Directory Permissions and Ownership

Next, you need to verify the permissions and ownership of the home directory. Run the command ls -ld /home/username to check these details. The output should confirm that the directory is a directory (not a file) and that the user owns it.

If the user does not own the directory, you can fix it using the command sudo chown username /home/username. The chown command changes the owner of the directory. If the user does not have read, write, and execute permissions, you can grant them using the command sudo chmod u+rwx /home/username. The chmod command changes the permissions of the directory, and u+rwx grants the user read, write, and execute permissions.

Ensuring Other Users Don’t Have Blanket Write Access

You also need to ensure that other users don’t have blanket write access to the home directory. Check this by running ls -ld /home/username again. If there are write permissions for others, you can remove them using the command sudo chmod -R go-w /home/username. The -R parameter applies the change recursively to all files and directories within the home directory, and go-w removes write permissions for the group and others.

Setting the User’s Primary Group

The primary group of the user should also be checked. Run groups username to check the user’s primary group. If it’s not set to the username, you can change it using the command sudo usermod -g username username. The -g parameter specifies the new primary group for the user.

Adding User to Additional Groups or Making Them an Administrator

Lastly, if you want the user to have additional group memberships or administrative privileges, you can add them to the relevant groups. Use the command sudo usermod -a -G group1,group2 username to add the user to additional groups. The -a parameter appends the user to the supplementary groups listed by -G.

To give the user administrative privileges, add them to the “admin” and/or “sudo” groups using the commands sudo usermod -a -G admin username and sudo usermod -a -G sudo username.

By following these steps, you should be able to fix the login issues with the newly created user account on Ubuntu. Remember, it’s crucial to replace “username” with the actual username of the account you’re troubleshooting in all the commands.
