We are an End to End IT Infrastructure Solutions company from India and we have been using Univention Corporate Server internally and also implemented to at least 6 more companies in the last 6 years (We are the partners of Univention for the last 6 years).
We have implemented both Free & Subscription based offerings of Univention. Some of the big implementations include for a very big Indian MNC, who is BSE Listed IT Distributor for 1650+ users spread across 11 Cities in India.
For this Organization, we have implemented UCS as Identity Access Management solution (if we can say - Linux based Active Directory Server) and also integrated SSO of Univention with their SAP, LinkedIn, Mail Server and VPN with 2FA.
For another customer, we have implemented as primary Domain Controller (this customer has not used Linux before) and their Windows Admin who is not comfortable with Linux, is also managing it as an Active Directory Server using RSAT without a single support call to us for the past 3 years.
The first installation that we have done was in the year 2015 and this Organization is using UCS as an Active Directory Server.
For another customer, we have implemented UCS is a giant in Biotechnology and involved in COVID Vaccine. For this customer, we have implemented UCS to integrate 4 different LDAPs to UCS and UCS as their Primary Authentication.
We are happy with Univention and hope to continue our relationship with them.
