Hi,

I'm using RHEL 4 with openssh 3.9.1 and I am authenticating to a Netscape DS (version 7 I believe). I can authenticate to the ldap server fine using ssh, but when I reset the user password and force the user to change that password at the next login, I no longer can authenticate, I keep being challenged for a password until it fails 3 times.

I have attempted using the latest ssh (4.2) and latest pam_ldap.so and this has no impact.

I can get the user to authenticate if I make the following change in /etc/pam.d/system-auth, However, the user will not be challenged to create a new password, they will just successfully authenticate with the temp password that was created during the password reset.

original:
account required /lib/security/$ISA/pam_unix.so broken_shadow

new:
account sufficient (rest is same as original)


system-auth:

If anyone has gotten password resets working in this environment I could certainly use some insight.

I do have this working in a RHEL3 using openssh3.6.1p2, but the combination of RHEL4 and any version of openssh3.6.1 to 4.2 does not allow authentication after a password reset...

Thanks
