OK, here's what we've put together: On the server that this is trying to ssh to and run a command, it gets an error: PAM: pam_open_session(): Cannot make/remove an entry for the specified session
The quick fix (which the SA's aren't willing to make long term is to comment out the line: “session required pam_loginuid.so” in /etc/pam.d/sshd. RedHat customer support thinks it's a bug but are not willing to call it so unless we can reproduce it with a native command line. Here's the output from the command being run in Ant: parsing buildfile jar:file:/var/lib/jenkins/tools/hudson.tasks.Ant_AntInstallation/ANT-1.9.4/lib/ant.jar!/org/apache/tools/ant/antlib.xml with URI = jar:file:/var/lib/jenkins/tools/hudson.tasks.Ant_AntInstallation/ANT-1.9.4/lib/ant.jar!/org/apache/tools/ant/antlib.xml from a zip file [echo] Creating a file in /my/path on myServer.myDomain to be sure there's something to delete [sshexec] Connecting to myServer.myDomain:22 [sshexec] Connecting to myServer.myDomain port 22 [sshexec] Connection established [sshexec] Remote version string: SSH-2.0-OpenSSH_8.0 [sshexec] Local version string: SSH-2.0-JSCH-0.1.54 [sshexec] CheckCiphers: aes256-ctr,aes192-ctr,aes128-ctr,aes256-cbc,aes192-cbc,aes128-cbc,3des-ctr,arcfour,arcfour128,arcfour256 [sshexec] CheckKexes: diffie-hellman-group14-sha1,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521 [sshexec] CheckSignatures: ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521 [sshexec] SSH_MSG_KEXINIT sent [sshexec] SSH_MSG_KEXINIT received [sshexec] kex: server: curve25519-sha256,curve25519-sha...@libssh.org ,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512 [sshexec] kex: server: rsa-sha2-512,rsa-sha2-256,ecdsa-sha2-nistp256,ssh-ed25519 [sshexec] kex: server: aes256-...@openssh.com, chacha20-poly1...@openssh.com,aes256-ctr [sshexec] kex: server: aes256-...@openssh.com, chacha20-poly1...@openssh.com,aes256-ctr [sshexec] kex: server: hmac-sha2-256-...@openssh.com, umac-128-...@openssh.com,hmac-sha2-512-...@openssh.com,hmac-sha2-256, umac-...@openssh.com,hmac-sha2-512 [sshexec] kex: server: hmac-sha2-256-...@openssh.com, umac-128-...@openssh.com,hmac-sha2-512-...@openssh.com,hmac-sha2-256, umac-...@openssh.com,hmac-sha2-512 [sshexec] kex: server: none [sshexec] kex: server: none [sshexec] kex: server: [sshexec] kex: server: [sshexec] kex: client: ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 [sshexec] kex: client: ssh-rsa,ssh-dss,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521 [sshexec] kex: client: aes128-ctr,aes128-cbc,3des-ctr,3des-cbc,blowfish-cbc,aes192-ctr,aes192-cbc,aes256-ctr,aes256-cbc [sshexec] kex: client: aes128-ctr,aes128-cbc,3des-ctr,3des-cbc,blowfish-cbc,aes192-ctr,aes192-cbc,aes256-ctr,aes256-cbc [sshexec] kex: client: hmac-md5,hmac-sha1,hmac-sha2-256,hmac-sha1-96,hmac-md5-96 [sshexec] kex: client: hmac-md5,hmac-sha1,hmac-sha2-256,hmac-sha1-96,hmac-md5-96 [sshexec] kex: client: none [sshexec] kex: client: none [sshexec] kex: client: [sshexec] kex: client: [sshexec] kex: server->client aes256-ctr hmac-sha2-256 none [sshexec] kex: client->server aes256-ctr hmac-sha2-256 none [sshexec] SSH_MSG_KEX_ECDH_INIT sent [sshexec] expecting SSH_MSG_KEX_ECDH_REPLY [sshexec] Permanently added 'myServer.myDomain' (ECDSA) to the list of known hosts.

Just not running it TO RHEL 8. Thus if I could reproduce it in a way that the RedHat folks could reproduce it on their end, then I may get a fix for it other than commenting out the PAM module.
