Hello everybody,

I have a question about the limit of the length of account name that is at 18
Account name is too long, length(xxx....) > 18

Is there a particular reason of this ? Can it have edge effect if I change the value ?

Thanks in advance for your replies,
FlochonR

This is a technical limitation, linked to the fact that Linux usernames can't have more than 32 characters, and The Bastion uses prefixes and suffixes internally that add to the base length of the account you want to create.

We might want to optimize the length of these prefixes/suffixes at some point to try to get back room for a few more characters, but it won't be more than 4 or 5, unfortunately.

EDIT: I was thinking about group names when answering above (it's 18 chars too). It might be feasible to have slightly longer account names, maybe up to ~28 (the 32 chars limit still applies, and there is a --tty suffix of 4 chars), I'll investigate.

FWIW it was easier than I previously though, #214 will bring the limit up to 28 chars.
