I have a laptop that works rather well with Linux, but the wireless connection, working fine at home, has issues on an access point that uses AD-based credentials to grant access. In some failed logins, I saw somewhere an error about expired certificates. Since this time, I never managed to login with the same credentials I used previously. My question: Where are those files, so I could find the one from this access point and remove it, so it gets downloaded again ? I suspect that those files have a very short lifetime, like a week. Once I find which one it is, I could put a line to delete this file when booting the laptop. BTW: This is the Algonquin College wireless network, which uses my AD credentials. And those seem to be based on Microsoft 365. Thanks :-) -- Geek, c'est ma nature Linux, c'est mon choix !
