Briefly question. As the title shows of, Im searching for a possibility to config openWRT so that only one client connection will be allowed over an access point. Further connection trials should be rejected if one client is connected already. Is this possible by configuration only within the openWRT config?
" ... client connection ..." is not specific enough. You mean, one client only at a time allowed to connect via Wifi ?
Anyway, you can limit the number of concurrent users with the help of a Captive Portal, i.e. coova-chilli. Needs radius support, then.

There is a maxassoc setting possible in the config file. I didn't see a way to set it in the GUI.
If it is one specific device you want to allow to connect you could use a MAC list in allow mode.

You didn't specify but will this one client be the same everytime? If so one way is to use MAC address filtering, and only use the one MAC address for the one client

First of all, thanks a lot for your quick replies. Normally it shouldn`t be the same device that will only be connected to the WiFi AP. It should be as mentioned by reinerotto just one device at the same time that can connect to it. If a second, third etc. device will try to connect too, it should be rejected.
You could configure DHCP so that there is only one IP address available.
