Hi,
When setting the SSHD log level to verbose as recommended by the CIS, I get the following in the secure log :
Dec 17 11:32:29 myserver sshd[8456]: Connection from xx.xx.xx.xx port 44090 on xx.xx.xx.xx port 22
Dec 17 11:32:30 myserver sshd[8456]: Accepted key RSA SHA256: qhpzQKKbwaX8 found at /usr/bin/sss_ssh_authorizedkeys:1
Dec 17 11:32:30 myserver sshd[8456]: Postponed publickey for myuser from xx.xx.xx.xx port 44090 ssh2 [preauth]
Dec 17 11:32:30 myserver sshd[8456]: Accepted key RSA SHA256: qhpzQKKbwaX8 found at /usr/bin/sss_ssh_authorizedkeys:1
Dec 17 11:32:30 myserver sshd[8456]: Accepted publickey for myuser from xx.xx.xx.xx port 44090 ssh2: RSA SHA256: qhpzQKKbwaX8
Dec 17 11:32:30 myserver sshd[8456]: pam_unix(sshd:session): session opened for user myuser by (uid=0)
Dec 17 11:32:31 myserver sshd[8456]: User child is on pid 8460
Dec 17 11:32:31 myserver sshd[8460]: Starting session: shell on pts/4 for myuser from xx.xx.xx.xx port 44090 id 0

What are the corresponding events in audit ?
My main concern is with the bold line which indicates how the public key was granted

Could you point me to a documentation showing which events a ssh login would generate ?

Regards
Philippe
