LDAP kills network.

If I use the "system-config-authentication" tool to enable LDAP, my network becomes unreachable. I can't use telnet, ping, nor LDAP itself. I cannot connect to anything on the LAN.

Except the client host itself. Ping localhost, 127.0.0.1 and its own ip on the lan (192.168.0.20) work.

"system-config-authentication" changes 6 files:
nssswitch.conf, 4 files in pam.d, and sysconfig/authconfig.

Something causes intolerably slow performance in F11

During boot, setting up the message bus and sendmail both take over 10 min to get past.
avahi-deamon,HAL
After boot, the system is so slow that SSH connections time out.

I'm disabling sendmail, avahi-deamon, bluetooth,ip6tables,iptables,ntpdate.

I 'm also removing all bluetooth software.

LDAP or kerberos smashes server

I enabled LDAP and Kerberos, and not it takes over an hour to boot up and log on.
Can't log on with SSH,connection times out.

VMWare Tools on F11

Even if you've installed kernel-devel and kernel-headers, you must make a symbolic link :
su -c 'ln -s /usr/src/kernels/.- /usr/src/linux'

In my case it was:

ln -s /usr/src/kernels/2.6.29.6-217.2.8.fc11.i586 /usr/src/linux

This leave a mystery abouy the i686 arch though...

Stuck on Namerserver configuration

The config infrastructure on named has changes somehow, so copying the files from F7 to F11 has no effect.

Fedora 11 Server

I'm configuring a new Fedora LDAP/Kerberos/BDC. I'm trying everything on a virtual machine from VMWare first. Here are some of what I had to do:

)When installing from the ISO, disable all packages, BUT DO use/enable the latest update repositories. Otherwise, installation may fail, or you may never get it configured correctly.

)Be ready to fix the selinux problems, when you enable LDAP. You need at least
semanage port -a -t ldap_port_t -p tcp 11562
semanage port -a -t ldap_port_t -p udp 11562
setsebool -P allow_polyinstantiation 1

)remove the rhlgb from the kernel parameters in grub.conf
