This appears to be a bug. The tomcat user is a system account and not a user account. There is now way that it should be displayed on your login screen. I had a similar issue when I installed KVM. It listed "Libvirt Qemu" as a user on login screen. The issue was reported as a bug on launchpad:

https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1672112

If you get annoyed by a particular user appearing on your login screen. You can see the following post to hide a user from login/welcome screen

How do I hide a particular user from the login screen?

This is how I fixed mine on Ubuntu 16.04:

Change UID to a value lower than 1000 so user will be hidden by lightdm:
```
sudo usermod -u 998 tomcat
```
Do same for group id - GID"
```
sudo groupmod -g 998 tomcat
```
Since tomcat won't have access to the /opt/tomcat modify or reset ownership:
```
sudo chgrp -R tomcat /opt/tomcat
```
Please note that in step 1 above terminal will display process id that used by tomcat. Kill them and start from step 1:
```
sudo kill -9 <process_id>
```

Note:

You can get the tomcat process id's with:

ps -eLo pid,ppid,stat,euser | grep tomcat

And the new UID I used id purely random pick that which is ok by you.
