Key Projects Accomplished

1. Development of File Persona Authentication Component Duration : February 2017 to till date.

Project Description :

File Persona is a feature of HPE 3PAR OS that enables a rich set of name services for authentication along with file protocols on an HPE 3PAR StoreServ system. File Persona supports three types of name services for authentication — Active Directory (AD), LDAP, and Local Database for local users and groups. It supports Kerberos, NTLMv2, and NTLM for Active Directory authentication. File Persona uses the local user authentication method by default, but Active Directory and LDAP services can be added to the authentication stack for the user and group name lookup. The authentication stack order can be configured from the StoreServ Management Console (SSMC) and selecting the correct order optimizes the performance of account name lookups.

Operating System : Windows XP/7/10/2003/2008/2012/2016, RHEL 5, 6, 7, CentOS 6, 7. Tools : GDB, Valgrind, Wireshark, Load DynamiX, Clumsy 2.0, Meatgrinder, Github, Bugzilla.
