McDermott has agreed an ongoing deal with the Rhinos instead of a traditional coaching or playing contract, which the reigning Super League champions claim is a first in professional sport. Chief executive Gary Hetherington said the announcement will prevent any speculation over his future.
"There are no jobs for life for any of us but it's for the foreseeable future," Hetherington told Press Association Sport.
"There is no time limit so it takes away all the speculation and it gives us confidence in terms of our longer-term vision and plans. Brian McDermott is at the heart of all those plans and it's important that he can see the way forward in terms of putting them into place.
"The club is going through a transition from the golden generation of players. We've seen exciting players emerging and cementing their places in the squad and Brian has been a part of that. It's recognition that Brian is part of the furniture at Headingley Carnegie. He has got a tremendous record here and is very hungry for a lot more success in the future.
"It's probably a first. I'm not aware of any other similar arrangement in sport. We do put end dates on most people, certainly players and indeed coaches, but we don't see a need to do that with Brian."
McDermott was on a three-man, all British short-list for the role of national coach when former Leeds boss Tony Smith stepped down in 2009 but lost out to Steve McNamara, whose contract is up at the end of this year's World Cup. McDermott's stock has risen considerably since after winning back-to-back Super League titles.
Hetherington agreed to release Smith from his Rhinos contract in 2007 to enable him to succeed Brian Noble as Great Britain coach and says he would have no problem doing the same with McDermott.
"We are big supporters of progression for players and staff and, if such an opportunity were to ever arise in the future, we wouldn't stand in anybody's way," Hetherington said.
"If you remember, that happened with Tony Smith a few years ago."
