Re: User Authentication with nslcd 0.8.13

I am not seeing any errors in particular from nslcd. Do I need to install certificates?

Hi All,

I am trying user authentication with LDAP with nss-pam-ldapd on an arm-based client. The LDAP server is all set up. I tried querying the server from the client using ldapsearch and it returns the entries correctly. However logging in to the client doesn't work. Has anybody faced this problem before? i'm using nss-pam-ldapd version 0.8.13.

Here's what I got when I ran nslcd in debug mode:

That SIGINT is just me doing a Ctrl-C on keyboard. Any help is appreciated.
