[OpenSIPS-Users] Memcache and calculate_ha1 disabled

[Bogdan-Andrei Iancu]

Hi Takeshi,

The tutorial was written for the case where you provide the plain-text 
password and the auth engine calculates the ha1.

If you want to disable the HA1 calculation, in that case you need to 
cache it and to provide it to auth engine via the password AVP (for pv 
authentication).

Actually, aside of changing the "calculate_ha1" param , you should not 
change anything else - if your changes are consistent (like adding in 
"password" column in DB the HA1 value), the caching mechanism will work 
unchanged - it will load, cache and provide the HA1 instead of passwd.

Regards,
Bogdan
