Can a WLC query to a SQL Server as external database???
We have a project in which our customer wants to use the WLC Guest portal and use its SQL Server Database as external database (LDAP Database). My knowledge about it is poor. I know that works with LDAP databases but I don´t know whether it is also compatible with SQL Server or the schema is different and maybe we require a development to integrate the SQL Server's data into a LDAP database and, in this way, query for the users contained in this database.
In some Cisco documents I could read about the support for SQL ( WLC Best Practices) http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/82463-wlc-config-best-practice.html#anc9 ; but I didn't found any information about how do it.
Well the short answer is sql directly no, buuuut :)
What you can do is use a radius server that supports the sql flavour you like, as a backend, i personally default to freeradius since it can be connected to most flavours of database either natively or via odbc, plus it's free and very customizable.
