Job Competencies

Tools, platforms and technologies:
- LDAP technologies – Project(major/principal)
o The purpose of this project is to complete a AD/LDAP migration of all Unix OS Platforms/systems to an LDAP server/client services; legacy used flat files, NIS+, and DCE; this is standardizing to a Single Sign-On. This includes all Unix development, staging, and production environments.
o UAL is standardized on Microsoft Active Directory
o Unix Engineering comprises of multiple Unix OS Platforms: HP-UX, AIX, Solaris, RHat & SuSE Linux, OpenVMS
o Each of the Unix Engineering teams have participated in a conversion from DCE(or flat files), the reconciling of UIDs and the installation and implementation of LDAP following standard documentation. This documentation is available on an Eng internal site for their use as we continued converting their servers to single-signon. sUA HP-UX and sUA AIX are completed, all remaining Unix OS systems need to be converted as well.
o Need to develop a set of procedures that System Administrators and departments can follow to facilitate the following:
§ Creating LDAP groups that provide access to UNIX servers.
§ Adding/removing user and shared accounts to/from LDAP groups.
§ Populating the UNIX portion of AD for new users, which includes assigning them unique UNIX UIDs and primary GIDs; assigning them to the proper LDAP groups for proper server access; and adding them as members to the proper UNIX groups.
§ Populating the UNIX portion of AD for existing user and shared accounts that were not accessing UNIX servers but now require access, which includes assigning them unique UNIX UIDs and primary GIDs; assigning them to the proper LDAP groups for proper server access; and adding them as members to the proper UNIX groups.
§ Creating new UNIX shared accounts to AD, which includes assigning unique UNIX UIDs and primary GIDs.
§ Adding user and shared accounts to UNIX groups within AD.
High level LDAP Integration steps:
Integration Steps Description
HPSA Update “Description” field to match the use and the role of the server, this will help accomplish step #3.
Ports Ensure client network ports 389 and 636 are open to (,,,,, both TCP and UDP. For Solaris, port 88 for Kerberos.
