Equation of Motion of Spin Connection: Help Needed

[shereen1]

Dear All
I am trying to find the equation of motion of the spin connection out of the einstein hilbert action written in terms of the vielbeins. Can anyone help me to do?
Thank you

Page 8 and 27/28. You should find the usual constraint for the spin connection, eqn. (20).
