Need help on FreeRadius+OTP+OpenLDAP integration

[pradyumna dash]

Hi,

I need a documentation on how to implement  FreeRadius+OTP+OpenLDAP, I
have installed and configured FreeRadius+OpenLDAP before but never
used OTP, and also would like to know how OTP will be configured with
SASL and how does SASL auth store OTP parameters.

Another problem am facing is, first there is an authentication with
freeradius but the next thing that is triggered in pam.d/ssh is the
"account" section for authorization and here OpenLDAP requires
password for the second time.  So a user needs to login twice because
of this.  How to solve this issue

Please help me out to solve this issue.
