The latest release of nss_ldap (nss_ldap-199) and pam_ldap (pam_ldap-151) support HP-UX 11.x.
As HP already have their own LDAP solution as part of the LDAP-UX package, there is less reason to use the PADL modules on HP-UX than on (for example) AIX. We are however providing this enhancement at the request of several customers.
The installation procedure for these modules is essentially the same as for Solaris: run the configure script with the appropriate options to detect your LDAP client library, and then make followed by make install. HP-UX uses a different shared library extension to Solaris.
Note that you cannot use an LDAP client library that links against libpthreads, as HP-UX will not dynamically load libraries that require thread local storage. Netscape and iPlanet SSL-enabled LDAP libraries require libpthreads. We suggest you use OpenLDAP libraries if you require SSL support for nss_ldap or pam_ldap.
If you are statically linking SSL libraries into nss_ldap and pam_ldap, ensure that the SSL libraries are compiled position independent (gcc option -fPIC) and all symbols are loaded into the LDAP libraries (ld option -Fl for each library).
