There's 2 possibilities here:
1. Your zip file doesn't contain exactly what you think it does. If your zip doesn't have a file named `x-pack-extension-descriptor.properties` at the _root_ of archive, then you will get this error. **This is the most likely cause**. Check the contents with a command line zip tool. If you don't have anything else available, you can do this with `jar tf CustomRealmPlugin.zip`
2. Something about your filesystem is causing problems. This happens occasionally, but is far less likely. Trying manually checking that your current user can create the directory `D:\elasticsearch-5.6.10\plugins\x-pack\extensions\.installing-3375002382823345241` and then write the `x-pack-extension-descriptor.properties` file in that directory.

Thnkss TimV.
1. Can you tell me what should be the contents of my zip file.
2. The user which I am using can create directory. How to check whether my user can create that inside directory or not(.installing-\*).
Thanks.

For the purposes of this issue, the important part is what I replied earlier - your zip needs to have `x-pack-extension-descriptor.properties` at the root of archive.
