rlm_pap and support of SCRYPT hash ?

Hello

today we use FreeRADIUS Version 3.0.16 on "Ubuntu 18.04 LTS"

recently, for security reasons,  we change the hash of passwd in our 
ldap directory from {SSHA} to {CRYPT}*SCRYPT *but EAP/TTLS/PAP no longer 
works

Indeed, man rlm_pap talks about crypt but not *scrypt*

I installed a new test VM host with FreeRADIUS Version 3.2.5 on "Ubuntu 
24.04.2 LTS"
It works fine now but I don't know if it's due to the new version of 
freeradius or the updated crypt libraries for exemple ?
Even in this version, man rlm_pap talks about crypt but not *scrypt*
In /usr/share/doc/libcrypt-dev/README.md.gz for exemple I find 
effectively that SCRYPT is supported

Can you help me answer this question? Thank you, Bregards Marc
