In active directory the attribute edsaAzureGroupDisplayName exist. What does the first 4 characters (edsa) stand for? Is it an acronym or short form of something?
A legacy name for Active Roles is the "Enterprise Directory Service".
EDSA is short for "Enterprise Directory Service Attribute" and EDSVA is short for "Enterprise Directory Service Virtual Attribute".
As a general rule of thumb, an EDSA attribute is computed, and is used to display something in a more user-friendly way. For example: edsaAccountIsDisabled is a Boolean which displays the current disabled/enabled status and allows someone with the necessary access to set that status easily. This is much friendlier than a bitwise mask on the userAccountControl attribute.
An EDSVA attribute is a virtual attribute which holds some value. For example: edsvaDeprovisionStatus is an enumeration which holds a value which displays the current Deprovision status and allows someone with the necessary access to set that status.
