Hi, we have recently upgraded to ArcGIS 10.6 and are having problems editing sde feature classes using Windows security groups. If a user is added with individual permissions they can edit, but not when they are only part of a group. Has anyone encountered a similar issue?
Are the users in the groups with issues from within the same domain or nested in another domain?
What version is your SQL Server level (select @@version) and version of the Enterprise Geodatabase?
Which version of ArcGIS we're you using before 10.6?
This sounds a lot like the problem existing in 10.5.1, for which the SQL Server permissions patch was released. Would be too bad if the same issue resurfaced.
