Dear Maintainer,
when attaching to a screen that is owned by a different user with a long
name (> 20 characters), I get the following error:
host ~ # screen -x this-is-a-very-long-username/
Screen owner name too long - sorry.
screen originally had a limit of 20 characters for usernames and
wouldn't work at all if your username was longer, but this was mostly
fixed in a Debian patch. Apparently the patch overlooked this specific
situation so that this issue still occurs.
I've attached a patch that resolved this issue for me.

Description: fix "Screen owner name too long - sorry" error
The patch 49long-usernames.patch increases the maximum user name length that
screen supports from 20 to 50 characters. Unfortunately, the limit still
applies when trying to attach to a multiuser screen:
.
host ~ # screen -x veeeeeeeeeeeeerylongusername/
Screen owner name too long - sorry.
.
This patch raises the length limit for owner names too.
.
