restart:

Eq1:=(-1/k)*B*(diff(-f(r),r$3)-(1/(r+k)^2)*diff(f(r),r$1)+(1/(r+k))*diff(f(r),r$2)+(1/(r+k)^2))

-((r+k)/k)*B*(diff(-f(r),r$4)+(2/(r+k)^3)*diff(f(r),r$1)-(2/(r+k)^2)*diff(f(r),r$2)+(1/(r+k)^2)*diff(f(r),r$3)

-(2/(r+k)^3));

bcs:=f(-h)=1/2,(D@@1)(f)(-h)=1,f(h)=-1/2,(D@@1)(f)(h)=1;

dsolve({Eq1,bcs},f(r));

Please have a look.

Thanks
