If you install on Yosemite, you need to do a full install of FMS13 on the machine.

The reason is that with the updater, it does not completely write everywhere it is needed.

So, you should un-install the FMS with the installer. Then trash the entire FileMaker Server folder and then re-install with a full installer.

After that, everything should be working fine.

 

...and yes, we have a handful of Yosemite servers with CWP, WD working just fine.

 

there is ways to do some edits in several files, but re-install with the above recommendation, will probably be faster....

 

Oh, and make sure that you backup your datafiles, scripts, plugins, webfiles before you trash the FileMaker Server folder...

Using some info from this discussion and other information from Kerio and Maxum I was able to set up all FileMaker Server, Kerio Connect, and Maxum Rumpus all on a Mavericks server while letting OS X Server.app Web, Wiki, Profile Manager and VPN still do their thing properly.

I wrote up a brief but illustrated tutorial that comes with some customizable example files and posted it to the Tutorials section of the RAIS page: http://rais.precursor.ca

after much fideling around, vhost settings in fms, two IP numbers, all to no avail, since osx server always takes over httpd... I tried this approach..... And it works like a charm! Thanks precursor!
