[nssldap] Failed to bind to LDAP server - Can't contact LDAP server only on certain programs

[Larry Low <llow [at] telesphere.com>]

I have this odd problem I've never been able to track down.  I use nss_ldap for 
passwd, shadow, and group and it works correctly nearly all the time.  I only 
have problems with one perl application which always triggers this.  The 
program in question is Smokeping.

perl: nss_ldap: failed to bind to LDAP server ldaps://x.x.x.x:636: Can't 
contact LDAP server
perl: nss_ldap: reconnecting to LDAP server (sleeping 8 seconds)...
perl: nss_ldap: failed to bind to LDAP server ldaps://x.x.x.x:636: Can't 
contact LDAP server
perl: nss_ldap: reconnecting to LDAP server (sleeping 16 seconds)...
perl: nss_ldap: failed to bind to LDAP server ldaps://x.x.x.x:636: Can't 
contact LDAP server
perl: nss_ldap: reconnecting to LDAP server (sleeping 32 seconds)...
perl: nss_ldap: failed to bind to LDAP server ldaps://x.x.x.x:636: Can't 
contact LDAP server
perl: nss_ldap: reconnecting to LDAP server (sleeping 64 seconds)...
perl: nss_ldap: failed to bind to LDAP server ldaps://x.x.x.x:636: Can't 
contact LDAP server
perl: nss_ldap: could not search LDAP server - Server is unavailable

Any suggestions on where to debug?  After the last timeout the application will 
finally work.
