Red face Unusual ro filesystem state in FC5


I recently installed FC5. When I installed a Xerox printer driver I ran Redhat setup. By mistake, I must have put an "X" in the LDAP Authentication box, but, before rebooting, I didn't set up an LDAP server.

Then when I rebooted, I almost immediately get "can't find LDAP server" and the system comes up after a very long delay, complaining of "read-only file system." This seems to be due to the lack of an authentication server present. Mount -l shows the filesystem mounted in rw mode, but /proc/mounts shows that /dev/root (not in fstab or mtab) in ro mode and I can't write anything to disk, even to create a dummy text file with vi. I ran setup .. authenticate to find that LDAP authentication was mistakenly checked, but it can't be changed. I don't know what file Redhat setup wrote that boolean (LDAP authentication) configuration to or I could edit it in rescue mode with vi. I can't run setup in rescue mode, it won't allow me to execute binaries, other than a text editor. Can someone tell me what file the LDAP suthentication is written to by Redhat Setup and how to remount my /proc/mounts /dev/root filesystem in full rw mode after boot??? Thanks very much.

Problem solved. I'm posting to help others with similar problems.

I booted from FC5 DVD and entered rescue mode. From another forum post regarding LDAP setup, I looked at /etc/nsswitch.conf, using vi

It was:

passwd: files ldap
shadow: files ldap
groups: files ldap

I changed it to:

passwd: files
shadow: files
groups: files

And everything booted just fine!
