[gentoo-user] Fail to start slapd after reboot

[Dan Johansson]

Today I rebooted one of my servers and now slapd won't start (it's been 
running OK until this reboot). The is what the slapd.log says:
-------------------8<-------------------------

I've tried to restore a backup from before the reboot - but I still have the 
same problem. Any suggestions on what to do to solve this?
