ssh + ldap issues

[Lev Lvovsky]

In an effort to install cfengine (which requires 0.96b + of ssl), we've 
had to recompile all sorts of related packages on our RedHat 6.2 boxes. 
  In addition, we're trying to implement an LDAP directory.  Basically 
the source RPMS for RedHat 7.3 were installed and compiled on a 6.2 box 
to get this all to work.

We're running into the following problem on the 6.2 boxes after having 
compiled/installed openssh-3.7.1p2 with the spec file in the contrib 
directory.  Upon attempting to use an LDAP username with ssh, ssh, we 
get the following output in the logfile:

------

net-pf-10

dlopen(/lib/security/pam_ldap.so)

failure; logname=root uid=0 euid=0 tty=ssh ruser= rhost=login-server
------

The above-referenced file pam_ldap.so does exist.  All other LDAP 
related applications (su, ldapsearch, etc...) work, and are able to 
authenticate the user.

Not sure if any more info is necessary to diagnose the problem, but any 
help would be appreciated.

thanks,
