Thanks for the reply amade.

I tried ./configure --enable-pam but had the same result.

I used your return; suggestion in Authenticate() and it's working.

I need truecolor support which is why I'm using the development branch.  When the feature lands in a tagged release, I'll switch over to that.  Thanks again.

master is development branch for v5

if you want something close to 4.5.1 please use screen-v4 branch

if you really want to use master, either comment out stuff in authentication.c (make Authenticate() just "return;")
or try building with PAM support (./configure --enable-pam)

Summary:  Feature works correctly on current screen builds and tags up to v4.5.1.

In the 4.99.0 however, after detaching a screen and attempting to reattach with:

./screen -x screenname

The output is:

can't open passwd file
can't open passwd file
can't open passwd file

It's either something to do with seteuid() or perhaps the fact that the screen storage directory changed to ~/.screen.

The build process used was identical between v4.5.1 and v4.99.0.

I have tested and have reproduced this problem on:
- Ubuntu 14.04.5 LTS
- Ubuntu 16.04   LTS
