1. Log into the server via SSH.

2. Execute the command below to found the ID of the johndoe user:

   # grep “johndoe” /etc/passwd | cut -d: -f3

   10001

3. Using the user ID found the in step №2, run the command below to find a user with the duplicate ID:

   # grep “10001” /etc/passwd

   exampleuser:x:10001:1003::/var/www/vhosts/example.com:/bin/false
   johndoe:x:10001:1003::/var/www/vhosts/example.com:/bin/false

4. Using the vi text editor open the /etc/passwd file and move the correct system user johndoe up in the list (above exampleuser user):

   • Before
     

     exampleuser:x:10001:1003::/var/www/vhosts/example.com:/bin/false
     johndoe:x:10001:1003::/var/www/vhosts/example.com:/bin/false

   • After
     

     johndoe:x:10001:1003::/var/www/vhosts/example.com:/bin/false
     exampleuser:x:10001:1003::/var/www/vhosts/example.com:/bin/false

5. Save changes.

   # chown -R johndoe /var/www/vhosts/example.com/
