Good morning,
many thanks for the feedback. Unfortuantely I’m limited to SLES10SP2 in my environment but I’m very much looking forward to a fix in the next release of the nx software.
I’ve done an strace incl. childs could see that the pam modules seem to be properly loaded. Username and password are correct and also correctly transmitted from client to server. Please find the strace as txt attached. Maybe it helps.
Thanks for the answer. “su” is working fine, I could switch from root to user, from user to user etc. with su – <username>. Here’s the default /etc/pam.d/su config used on the SLES10SP2 server:
#%PAM-1.0
auth sufficient pam_rootok.so
auth include common-auth
account include common-account
password include common-password
session include common-session
session optional pam_xauth.so
I checked the error “nxexecPAMCheckCredentials: Authentication failed with error 28.” on the nxerror.log which I think is the hint for the problem (at least mine). The /var/log/messages shows:
Jan 9 08:49:25 server nxexec: PAM unable to dlopen(/lib/security/pam_unix2.so)
Jan 9 08:49:25 server nxexec: PAM [error: /lib/security/pam_unix2.so: undefined symbol: pam_syslog]
Jan 9 08:49:25 server nxexec: PAM adding faulty module: /lib/security/pam_unix2.so
NX added a PAM configuration in /etc/pam.d/nxsshd which look fine for me. From what I understood about PAM it should be able to use local /etc/passwd,/etc/shadow, NIS and LDAP.
Hello,
I’m also having troubles with the authentication when using NX 4.
Setup – NX client Ubuntu 12.04 nomachine_4.0.369_1_i386 / NX server SLES10SP2 nomachine_4.0.369_1_i686. I’m using the standard setup after installation without any modifications:
