RE: Problem with my ldap server and users

[<poberli@hsr.ch>]

Hello Buchan and hello Quanah

Thank you for your mails.
I was now able to fix it, but first some more details.

The server crashed the day before, so it wasn't shutdown cleanly. After
the server was rebooted and slapd started again, did it overwrite one of
the log.0000xxx files (the one where it was restarted the last time
correctly). I tried to fix it then with a db4.2_recover, but because one
of the logfiles was missing (overwritten by a new one) was that not
anymore able.
I was only able to fix it by deleting the whole database and
re-importing everything again :(

I do now a daily restart of the database, so at least this issue should
be fixed.

I don't yet upgrade the version, because I want to keep the debian (3.1)
package so that I'm able to use apt-get to update my system. If debian
decides to update to 2.3 then fine :) but I guess they won't in this
version.

Anyway thanks for your help, I learned once again a lot about LDAP!

Cheers,
Patrick
