We have around 20+ accounts of different services (company email inboxes, forums, social media, Github, etc.) we use in my team. For security reasons, whenever some employee leaves us, I need to change the password for all those services. Luckily, it's happened twice in a three years span, but it's still a pain.
How do you deal with shared credentials when an employee leaves? Especially if you're in a large organization where people are coming and leaving on a monthly basis. Many of those services don't provide LDAP integration, so even if we disable their account, they still have access to the service.
