## Symptoms

- The Gaia Clish commands "`show users`" fails with a "`Segmentation fault`" error.

Example 1:

```
Host> show users
Segmentation fault
```

Example 2:

```
Host> show users
segfault at ... rip ... rsp ... error
```

## Cause

The administrator configured a user ID for a user that was not created.

Output of the Expert mode command "`clish -c "show users" -d 5 > users_debug.txt`" shows that a password configured for a user without the required two entries:

* `passwd:<UserName>:homedir /home/<Home-Directory>`

* `passwd:<UserName>:shell <Shell>`

Example list of the required password entries in the Gaia Database (for the username "test1"):

```
passwd:test1 t
passwd:test1:gid 0
passwd:test1:homedir /home/test1
passwd:test1:lastchg 1639159429
passwd:test1:passwd *
passwd:test1:realname Test1
passwd:test1:shell /etc/cli.sh
passwd:test1:uid 0
passwd:tet11:uid 0
passwd:vcsa t
passwd:vcsa:gid 69
passwd:vcsa:homedir /dev
passwd:vcsa:passwd !!
passwd:vcsa:realname virtual console memory owner
passwd:vcsa:shell /sbin/nologin
passwd:vcsa:uid 69
```
