LDAPCon 2026 – Call for Proposals | Deadline: 15th June 2026 EoB
by project＠openldap.org 02 Jun '26

02 Jun '26

Dear Community, LDAPCon is the international conference on LDAP, held since 2007 and serving as a meeting point for directory services experts as well as specialists in Identity and Access Management. It is a three-day event, with the first day dedicated to workshops and the second and third days focused on the main conference program. The 2026 edition of LDAPCon is organised by Symas and DAASI International and will take place from 6 to 8 October 2026 in Tübingen, Germany . You use LDAP in interesting projects? You do LDAP client or server development? You have used LDAP in a new way? You do identity and access management (IAM) on top of LDAP? Why not share your ideas and experiences with others? We are looking for speakers who are willing to talk about any topic related to LDAP like: • LDAP implementations (servers, API, user interfaces) • LDAP Usage (Schema, Security, Operations, Scaling, big data) • Related technologies (PKI, XACML, SAML, SCIM, OAuth2, OpenID Connect, OTP) • LDAP and Beyond (IAM, Identity Federation, Identity as a Service, Internet of Things, Authentication on the web, Strong authentication) • Best practices for directory services We invite proposals for workshops (either 90 minutes or 3 hours) and presentations (45 min including at least 5 minutes for discussions). Be aware there will be also a slot for lightning talks (5 minutes), but there is no need to submit an abstract for that. You can spontaneously give a short talk. Join us in Tübingen for LDAPCon 2026 and help shape the conversation around the future of LDAP, directory services, and identity management. We are excited to receive your proposals and to welcome you for three days of insightful exchange. Please submit your proposals for consideration at → [ https://ldapcon.org/2026/cfp/ | https://ldapcon.org/2026/cfp/ ] Important Dates • Call for Proposals Closes: 15th June 2026 EoB • Notifications from the program committee: 15th August 2026 • Workshop Day: 6th October 2026 • Conference: 7th and 8th October 2026 We look forward to your contributions.
