problem with remote fonction

Hi,

I use a ispconfig's module to create clients and websites with th API. I have a problem when I would like to create websites, the website is creating but with the wrong owner: the client's default ( client0).

The output of
cat /etc/passwd/

web17:x:10017:10001::/var/www/clients/client0/web17:/bin/false
web19:x:10019:10001::/var/www/clients/client0/web19:/bin/false
web21:x:10021:10001::/var/www/clients/client0/web21:/bin/false

Each user is creating with the group of the client0 10001

cat /etc/group/

sshusers:x:5002:web1,.........web17,web19,web21
.
.
.
.
client19:x:10015
......

web17 and web21 are not in this file

The output of ispconfig.log

The problem comes from ispconfig don't add the group of the user in the website's creation.
When I change manually the owner I have this output

I use this same module to create domains on ispconfig and it's work well with the right owner only websites are this problem.
Thank you your help
