[rsbac] user management and one time passwords

[bine]

hey list,

i'm quite new to rsbac and wanted to play around with the user 
management. i can't find any options to set one time passwords for the 
users although i choosed it while configuring...does anybody here have 
experience with that?
i'm running 2.6.25.7-rsbac-1.4.0-rc1 to go kernel and have user 
management and one time passwords enabled.
the auth module is running and authentication over pam is working.
what am i missing?

best regards
bine
