If a user account has been deleted from the system without removing his/her home, the NX administrator who tries to add a new user with the same username will get an error similar to:

#/usr/NX/nxserver --useradd john --system
NX> 100 NXSERVER - Version 2.1.0-22
NX> 102 Password:
NX> 102 Confirm password:
NX> 500 ERROR: Execution of nxuseradd.sh failed when adding user: john.
NX> 500 ERROR: Cannot create directory `/home/john/.fonts': File exists
NX> 500 Cannot create directory `/home/john/.xemacs': File exists

NX> 500 Cannot create directory `/home/john/public_html': File exists
NX> 500 useradd: Copying of skel directory failed.
NX> 999 Bye

In this case, please:

1. Make a backup of the user's home directory, for example

    # cd /home
    # tar cvzf john.tar.gz john/

2. Remove the user's home

    # rm -r john/

3. Add the user

   #/usr/NX/nxserver --useradd john --system

In case of an error similar to the following, instead:

# nxserver --useradd john --system

NX> 102 Confirm password:
