@SecurityWriter I love it.
Yes, there are other #ldap alternatives out there. #activedirectory is not the only one. While this may be holding a lot of orgs back from switching, it's also important to recognize that many enterprise apps on both the desktop and server sides still require #microsoft #windows.
As a professional #sysadmin in the #banking industry many financial apps *only* support Windows. It makes sense to only deploy the OS where needed and/but there are complexities to managing heterogenous environments. Said complexities aren't always readily apparent either.
Having experienced a Windows to #Linux #desktop #migration years ago, I learned *a lot*. I am, however, all for ditching Microsoft but fully realize it's not always possible.
