Ssh authentication using 389 Directory server
I am trying LDAP authentication for users logged in CentOS by PAM. Also I have disabled(off) nsslapd-anonymous-access flag to restrict anonymous access by providing the binddn and bindpw.
I have changed binddn and bindpw in /etc/ldap.conf for PAM to bind with LDAP to authenticate user.
ie) When a user is trying to ssh pam will be communicated to bind with LDAP by reading /etc/ldap.conf to bind with LDAP to authenticate the corresponding user.
User authentication is not working every time. ie)some time the user is authenticated and sometimes the user is not authenticated.
i have verified the tools 389 FDS, nscd ,ssd, are properly running in CentOS.
I have tried by doing ldapsearch for the corresponding user. The result shows the user properly.

Thanks
Shriram.

You might "strace -0/tmp/thisdeamon.tr -p <this_deamons_pid> &" each daemon so you can see who did what when it intermittently fails. Add all the strace options you find appropriate. You can get a UNIX education reading strace/tusc/truss output.
