Comment 20 for bug 132473

Running NetworkManager with '--no-daemon' switch, I can see that WPA Supplicant isn't able to load the PKCS12 file.

This looks like :
---
OpenSSL: Failed to load private key
TLS: Failed to load private key '/home/ubuntu/lissyx.p12'
TLS: Failed to set TLS connection parameters
EAP-TLS: Failed to initialize TLS.
CTRL-REQ-PASSPHRASE-0: Private key passphrase needed for SSID wifi.reseau-local.fr
EAP: Failed to initialize EAP method: vendor 0 method 13 (TLS).
---

If I re-enter EAP-TLS configuration (when asked for the parameters right after this failure come into the logs), then, I get correctly connected and WiFi works like a charm ... until I disconnect/reconnect ... leading to the bug we're talking about.
