libssh2 1.5.0
attempting to use ssh items with key authentication fails with :
"Public key authentication failed: Callback returned error"
sshd debug log seems to indicate that zabbix did the disconnect :
testhost sshd[7540]: debug1: matching key found: file /home/zabbixtest/.ssh/authorized_keys, line 1 testhost sshd[7540]: Found matching RSA key: 80:22:56:01:b2:f2:20:f1:1a:5d:fe:de:78:d9:9f:f0 testhost sshd[7540]: debug1: restore_uid: 0/0 testhost sshd[7540]: Postponed publickey for zabbixtest from 127.0.0.1 port 39222 ssh2 [preauth] testhost sshd[7540]: Received disconnect from 127.0.0.1: 11: Normal Shutdown [preauth]
zabbix debug log does not seem to show much :
