Which system distro do you have? Which version of LSWS did you download? Any control panel on your system?

 

[Druciak]

System: PLD Linux https://www.pld-linux.org/
lsws-5.2.2-ent-x86_64-linux.tar.gz
without control panel

 

[Pong]

Which system PLD Linux based? CentOS? Ubuntu? Debian?
I just check the standard Linux distro:
all usermod has --a append option,

-a, --append append the user to the supplemental GROUPS
mentioned by the -G option without removing
him/her from other groups

while your distro doesn't.

bash-4.4# usermod -v
usermod (pwdutils) 3.2.19

maybe you should upgrade you usermod by using another rpm.
