Changing unix username

I am comparing ISPConfig with my existing Syscp setup.

If I am to transition, to make the change transparent I need to make the unix usernames user@domain

I've worked out how to do this manually in the database, in /etc/passwd and shadow and the postfix virtusertable

Is there an easier way to do this?

thanks,
Peter.

 

Linux does not allow the '@' sign in system usernames.
If other control panels use it, it means that they're using virtual users, not system users.

 

Thanks for that, of course you are right Falko. Looks like I'll leave the syscp server as it is and use ispconfig for new customers.

cheers,
Peter.

 

Hey Falko,
I'm running debian 3.1 sarge and am able to do a useradd with an @ in the username.
I was also able to ssh into the account with the -l option (as user@[email protected] wont work):
ssh -l [email protected] hostingsite.com
My /etc/passwd looks as follows:
[email protected]:x:10004:100::/home/[email protected]:

Would it be difficult to change the user format to _____@[DOMAIN]? Is there something else I might be breaking?

thanks in advance,
