Data Migration:

Perform data migration from the master server to the newly added server. Ensure data integrity and a smooth transition with minimal downtime.

Synchronization Assurance:

Monitor and verify that data synchronization is working correctly and efficiently across all servers in the replication topology. Troubleshoot and resolve any replication conflicts or synchronization issues promptly.

Maintenance & Support: Provide ongoing maintenance and support for the ISVD environment, including applying patches, performing upgrades, and ensuring high availability.

Documentation: Maintain accurate and up-to-date documentation of the directory infrastructure, including replication topology, configuration settings, and standard operating procedures.

Troubleshooting: Diagnose and resolve complex technical issues related to the directory service, including performance bottlenecks, authentication failures, and data corruption.

Collaboration: Work closely with other IT teams, including network engineers, security analysts, and application developers, to support and enhance the directory services.

in a Linux administration role, with a strong focus on directory services and identity and access management (IAM).

At least 3-5 years of hands-on experience

with IBM Security Verify Directory (formerly IBM Tivoli Directory Server or IBM Security Directory Server).

Required Skills and Qualifications:

Proven experience with the installation, configuration, and administration of IBM Security Verify Directory on

Red Hat Enterprise Linux (RHEL), SUSE, or other major Linux distributions.

Strong understanding of LDAP concepts, schemas, and best practices.

Expertise in configuring and troubleshooting ISVD replication topologies, including master-replica and peer-to-peer configurations.

Experience with data migration techniques, including ldifde, idsldapadd, idsldapmodify, and other directory-specific tools.
