Bug#457436: XDMCP stopped working
Package: kdm
Version: 4:3.5.8.dfsg.1-2
Severity: normal
--- Please enter the report below this line. ---
I am running a system with an attached thin-client. Some weeks ago all logins
at the thin-client failed.
First I thought it is because I did not update the thin-client for ages (it
happend once before that terminals running older versions of X
became "incompatible" with the server, e.g. keyboard selection stopped
working, ...). Now I updated the thin-client system and noticed that logins
still fail.
I even tested locally with Xephyr and noticed that XDMCP really stopped
working. You can reproduce the bug as follows:
- enable XDMCP in /etc/kde3/kdm/kdmrc
- allow a login window for any host in /etc/kde3/kdm/Xaccess
- restart kdm and log in
- open a terminal window and call "Xephyr :1 -ac -query localhost"
- try logging in
On a Debian stable system this works instantly. On a Debian testing system I
see the login window and can type in the user name and password. When
pressing the login button the screen just goes blank for a moment and the
login window reappears.
PS: I tested the same procedure with GDM and there I even do not get the login
window anymore. So maybe the bug is somewhere deeper in the system than just
KDM...
