server1からserver2にSSH接続しています。id_rsaファイルとid_rsa.pubファイルを生成しました。ssh to mike @ server2の場合は正常に機能しますが、ssh to john@server2はパスワードなしでは機能しません。mikeとjohnの両方のホームディレクトリには、chmod 700である「.ssh」が含まれ、そのフォルダには、以前に生成されたid_rsa.pubファイル(およびchmod 600)の内容のみを含む「authorized_keys」が含まれます。両方の内容は同じです。
サーバー1:Linux x86_64 x86_64 x86_64 GNU / Linux
サーバー2:AIX5.3.0.064ビット
コマンド1、ユーザーマイク(パスワードなしで動作):
ssh -v -n -o StrictHostKeychecking=no -o NumberOfPasswordPrompts=0 mike@server2 echo Hello
〜drwx------ 7 mike mike 4096 Jan 19 2011 .
〜/ .sshdrwx------ 2 mike mike 256 Nov 28 16:39 .ssh
〜/ .ssh / authorized_keys-rw------- 1 mike mike 823 Apr 06 11:56 .ssh/authorized_keys
コマンド2、ユーザーJohn(パスワードが必要)
ssh -v -n -o StrictHostKeychecking=no -o NumberOfPasswordPrompts=0 john@server2 echo Hello
〜drwx------ 12 john jgroup 4096 Apr 06 23:13 .

〜/ .ssh / authorized_keys-rw------- 1 john jgroup 414 Apr 06 11:55 .ssh/authorized_keys

なぜそれが1人のユーザーで機能し、別のユーザーでは機能しないのか(両方が同じサーバー上にある)について誰かが考えていますか?
