[Users] AVPops trouble

Hi I've been fiddeling with the AVPops module for some time now and havn't really gotten it to work as intended. I was hoping that someone out there might be able to explain the basics of the module, cause apparently I'm misunderstanding it... I think :-) I having trouble with pulling data from my openser DB with a scheme, and then pushing (pushto) it into a request header. The thing is I cant quite figure out, if I need to store the data I get from my scheme or if I can use it directly in a pushto! I have tried using a scheme: modparam("avpops", "db_scheme", "scheme0:uuid_col=contact;value_col=username;value_type=string;table=aliases") and then loading and pushing it with: avp_db_load("$from","s:pai/$scheme0"); avp_pushto("$P-Asserted-Identity","s:pai"); But this leaves me with no new field in the header, and nothing to show for in my MySQL log! I'm using these additional params for the AVPops: modparam("avpops","avp_url","mysql://openser:heslo@localhost/openser") modparam("avpops","avp_table","avptable") modparam("avpops","use_domain",1) The avptable is one I've created, since I wasn't sure if it needed to be there or not. Any and all help will be greatly appreciated, cause I'm really getting stuck here. Regards Martin
