Hello from Luis Flavio !! Is anybody on the list able to get LDAP working with PAM authentication on Linux/390? It looks that LDAP is working ok so far, since the users where cataloged and the authentication mode was configured using the "authconfig". So we belive that the getpwname is not interfacing correctly via PAM. The same process works ok on intel. We got the following result on Linux/390: May 23 15:51:53 Lxl010390 sshd[2141]: input_userauth_request: illegal user k294709 May 23 15:51:53 Lxl010390 sshd[2141]: Could not reverse map address 10.216.0.102.
