[ubuntu] 8.04 breaks samba file locking

Hi--

Just upgraded yesterday from 7.10 to 8.04.01. File locking in Samba is now broken, meaning two different users can have the same file open at the same time and edit it.

Server is RedHat 9.0 running Samba 2.2.7a-security-rollup-fix. This has been working well for us for several years. Have one WinXP box accessing the server using OOo 2.0. Have another couple of Win95 boxes.

In addition, have one Ubunutu 6.06 box, and three other 8.04 boxes.

It appears the XP and the 6.06 box lock files so the other cannot edit them while one has them open, but the 8.04 boxes, running OOo 2.4 can access and edit and save these files, thus causing havoc.

This is a production environment.

Can anybody suggest a solution or at least a trouble-shooting procedure?

Thanks!
