I'll start by saying I searched the archives, and didn't find mention of this - nor did I find any documentation that warned against it. But I figured it best to ask here.
We've got a single master and two slaves (one slave on our mail server for fast "local" lookups, and one on a beowulf cluster so it can be seen by the nodes on an internal network). All are running 2.1.29, master's OS is Fedora Core 2. I'm setting up a new mail server, and will be using Fedora Core 4 for the OS. I downloaded 2.1.29 and compiled it, but 'slapadd' segfaults instantly - an strace shows it looking in /etc/mtab, and then doing a 'munmap' just before it dies. I compared the libraries linked in to that with those on our current mail server (which is RedHat 8.0) and saw that the old server had no Kerberos libraries linked, so I removed the krb5-devel package and compiled again on the new system. Now it complains about the TLS configuration lines being "unknown directives" and still segfaults, so I guess I'll be putting krb5 back on there (sure enough, no SSL libraries are linked now). My question, has anyone run into this similar, and know of a solution? If not, then my big question is can I run different versions of OpenLDAP on the same network, in a master/slave configuration like this, and have them work okay? I don't know if anything has changed where it would be bad to, for example, run the latest OpenLDAP on the new server slaved to one running 2.1.29 as a master. Or maybe there's a specific version 'ceiling' where I could run up to a certain revision as a slave to that master without error, but if I go any newer it might cause problems (I'm not against staying a little behind in releases, if it's stable and the new versions don't add things that I need to operate here). In theory, I could upgrade the other servers to be the latest as well, but in practice that may be much more difficult than it sounds.
