This allows the enforcement of different permissions for different user groups, which is useful for scenarios such as:
Increasing upload limit for Jira administrators to handle exceptions.
Restricting user groups from uploading a subset of the allowed file types.
For example, if pdf is in the allowlist, set pdf maximum size to 0 to block the upload.
Setting different permissions for different groups of users
For example, Service Desk customers can only upload images and text files whereas Service Desk agents can attach more file types
Setting different size limits for different file types.
For example, to limit a maximum size of 100kb for image files, while other file types can be up to 10mb.
You can enable/disable file size check and edit the corresponding error message at Attachment Checker Configuration > File Size Checking tab.
To access the File Size Limit page, click Edit File Size Limit.
The default groups are:
jira-administrators (Can be changed)
jira-software-users (Can be changed)
jira-servicedesk-users (Can be changed)
jira-core-users (Can be changed)
jira-users (Can be changed)
logged in users
When a file is uploaded, it will check which group the user belongs to in sequence starting from group 1. For example, if user is a member of both group 1 and 2, the file size check will be based on limits set for group 1.
