PAP password check

[mic night]

Hello,

I have a freeradius server that i use to authenticate users before they 
access network switches. user passwords reside in an ldap directory with 
the following attributes and formats:

userPassword: (CRYPT password)
sambaNTPassword: (NT Hash)
sambaLMPassword: (LM hash)

PAP is choosing automaticaly the NT encryption to validate the password. 
Is there a way to force PAP to use the userPassword with the CRYPT 
encryption?

PS: i have to keep sambaNTPassword and sambaLMPassword along with 
userPassword as check items for other use scenarii.

i'll post the relevant part of my radius log file in case it helps, 
thank you.
