Hi Ulrich,

I thought the same, but it seems yum/dnf do not have a post-install 'hook', like debian has with DPkg::Pre-Install-Pkgs & DPkg::Post-Invoke, that allows you to define commands/scripts to run before and after.

Not sure how to do something similar on RHEL. I have now excluded openldap from auto updates, and added instructions on our manual update.instructions.

Any ideas here..?

I wonder: Couldn't some RPM "pre-script" remember the current permissions for some RPM "post script" to restore them (after they were messed up)?

Hi Ondřej,

Thanks for your reply.

Yes, we are putting our (single file) mdb straight in /var/symas/openldap-data, using subdirs never crossed our minds.

Anyway, we just have to document this behaviour in our upgrade documentation.

Must say: the behaviour, for us, is a little bit unexcpected. We didn't expect rpm upgrades to "mess" with fs permissions, but we can simply work around it.

Thanks again for your reply, appreciated!

    Hi,
    openldap-data is owned by the package and as such you'll have to

tell rpm somehow (a trigger, ...) that you don't want it to mess with it. AFAIK there's work ongoing to make the directory 711 which should sort things for you.

    That's unless you're putting the databases directly into
    /var/symas/openldap-data, we advise you create a subdirectory per

DB, e.g. /var/symas/openldap-data/dc=example,dc=com or /var/symas/openldap-data/cn=accesslog.

    Regards,
