Yesterday, after installing 12.10, I had the same problem in our office environment. Besides the above workarounds, I also read something about a problem of using gvfs on a nfs mount.
Today I started a brand new installation of 12.10, and activated the LDAP client ( apt-get install ldap-auth-client + auth-client-config -t nss -p lac_ldap) and mounted our NFS disk, containing our homedirs. (So, I didn't try #39) In a terminal I logged in with a LDAP-user and removed ~/.gvfs. I created /tmp/[username]/gvfs and made a symbolic link from ~/.gvfs to /tmp/[username]/gvfs. With lightdm, I logged in as this LDAP-user without any problems. (I assume that it is not related to this problem, but I also add /etc/modprobe.d/blacklist-floppy.conf containing "blacklist floppy". After a "update-initramfs -u" these annoying "I/O Buffer dev fd0" kernel messages dissapeared) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/870874 Title: LDAP user with automounted nfs homedir cannot login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/at-spi2-core/+bug/870874/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
