Hi all, this is a “theoretical” post. As written in the object: LDAP or mySQL in the
backend for a remote access control system? I’ve seen that that for remote access control, e.g.
Wi-Fi prepaid access solution, it is widely used freeRADIUS+captive
portal+mySQL. There are several implementation of capitve portals,
but they all do the same thing: act as NAS towards RADIUS providing AAA
attributes. User data are stored in the backend in a database,
but for usage characteristics this database should be a directory server (LDAP
server); such a solution, in fact, requires features typical for a directory
server: optimization for read operation, distributed model for storage of information,
advanced search capabilities. So the best solution should be LDAP (openLDAP)
for users’ data and SQL (mySQL) for accounting data (these data are
overwritten so number of write operations are almost equal to number of read
operations). Despite this, I’ve seen that LDAP is not widely
used. Is this for its complexity or are there deeper reasons that suggest to
use SQL database for both (user data, accounting) purposes? Does anybody have
links that might help to build a system made using this architecture? Regards, Carlo |
