Upgrade to KDE 3.0.5a-4 packages has solved crash problem. User information still not properly being established at login. Errors: id: missing name for uid xxxx id: missing name for gid xxxx there is a KDE 3.1.1a on ftp.kde.org for RHL 8. Does it fix this problem, if you upgraded to KDE 3.1.1a? No. After applying 3.1.1a user can not login. Have to use root access to kill off desktop_lock program. No sign that kcheckpass attempted to use pam_krb5 module. Any thoughts on which pam.d file this build is using? Additional note: Similar problem under RH9. Only worse.... root can not login either. This is using the same ldap.conf and krb5.conf files and same system dialogs to set settings. Additional note: Can not use nscd without total lockout issue on RH8. does it work if you change the permission of kcheckpass? chmod 4755 /usr/bin/kcheckpass Nope. suid on kcheckpass makes no difference. More info: The password prompt comes up with no username. A "kinit" is not being done when the screen is unlocked. Running kinit in a console will solve all 'problems' concerning the lack of system 'recognition' of the user. Errors: id: missing name for uid xxxx id: missing name for gid xxxx Issue resolved. Must run nscd as user root. Better to run nscd in 'secure' mode. Must do the following: 1) comment out server-user line in nscd.conf 2) change /etc/init.d/nscd line with secure="" to secure="-S passwd,yes -S group, yes" 3) change chkconfig line in /etc/init.d/nscd so as to setup valid start init levels, then chkconfig --del and --add Problems with RH9: ldap client programs crash. Can not run ldapsearch. Can not use ldap in nsswitch. gdb output: Program received signal SIGSEGV, Segmentation fault. 0x00000000 in ?? () (gdb) where #0 0x00000000 in ??

Can run kadmin, klist, create keytab, etc. assign to correct component Removing security severity. This is not a security issue. Red Hat apologizes that these issues have not been resolved yet. We do want to make sure that no important bugs slip through the cracks. Red Hat Linux 7.3 and Red Hat Linux 9 are no longer supported by Red Hat, Inc. They are maintained by the Fedora Legacy project (http://www.fedoralegacy.org/) for security updates only. If this is a security issue, please reassign to the 'Fedora Legacy' product in bugzilla. Please note that Legacy security update support for these products will stop on December 31st, 2006. If this is not a security issue, please check if this issue is still present in a current Fedora Core release. If so, please change the product and version to match, and check the box indicating that the requested information has been provided. If you are currently still running Red Hat Linux 7.3 or 9, please note that Fedora Legacy security update support for these products will stop on December 31st, 2006. You are strongly advised to upgrade to a current Fedora Core release or Red Hat Enterprise Linux or comparable. Some information on which option may be right for you is available at http://www.redhat.com/rhel/migrate/redhatlinux/. Any bug still open against Red Hat Linux 7.3 or 9 at the end of 2006 will be closed 'CANTFIX'. Again, if this bug still exists in a current release, or is a security issue, please change the product as necessary. We thank you for your help, and apologize again that we haven't handled these issues to this point.
