I got the external acl setup to work, it had some bugs but I notice something that maybe through configuration I can fix.
It's a configuration
external_acl_type CHECKOVERCUOTE concurrency=100 ttl=3 negative_ttl=10 children-max=50 children-startup=10 children-idle=5 %LOGIN /usr/lib/squid/ext_sql_session_acl --dsn "DBI:mysql:database=squidmgr" --user squidmgr --password squ1dmgr --table "proxy_usuario" --uidcol "identificador" --usercol "identificador" --cond "overcuote = 1" --debug
acl OVERCUOTE external CHECKOVERCUOTE
acl OVERCUOTE external CHECKOVERCUOTE
It generate: SELECT identificador AS 'user', '' AS 'tag' FROM proxy_usuario WHERE (identificador = ?) AND overcuote =1
UID queried: 'frizquierdo - ' # when user identifier authenticated on squid is 'frizquierdo'
The user identifier generated by the ext_sql_session_acl query is made up of the user identifier +space+ hyphen +space, for example (for 'frizquierdo' identifier, 'frizquierdo - ' is generated), so in the database it would have to be the user identifier stored in that format.
Is there a directive that guarantees that the parameter is not created that way?

In my previous email I was missing part of the text when I sent it, I
deleted it by mistake.
This is what I have so far:
I try to make the following config:
external_acl_type CHECKOVERCUOTE ttl=5 negative_ttl=5 children-max=10
children-startup=5 %ACL /usr/lib/squid/ext_sql_session_acl --dsn
"DBI:mysql:database=squidmgr" --user squidmgr --password squidmgr --table
"proxy_usuario" uidcol "id" --usercol "identificador" --cond "overcuote=1"
--persist
acl OVERCUOTE external CHECKOVERCUOTE
http_access allow CONNECT SSL_ports !dominio_cuba usuarios_internet
macs_red_local red_local !OVERCUOTE
--cond "overcuote=1" is the field in database that it's set to 1 when user
calc overcuote.
if i try ext_sql_session_acl from terminal, i see:
ERR message="unknow UID ' '"
