[Users] AVPOPS manipulating header fields

[Bogdan-Andrei Iancu]

Hi Martin,

do not use the from uri as a string uuid to perform loading, but use it 
as key (username, domain):
    avp_db_load("$from","s:pai/$scheme0");   in 1.0.x
or
    avp_db_load("$fu","s:pai/$scheme0");   in 1.1.x

in DB you will have to populate the username and domain fields instead 
of uuid.

regards,
bogdan
