Please send backport.

@lunny I'm not sure but does this allow any user who can create issues to edit other user's issue descriptions?

[lafriks]

@brunoais no, it allows users with write access to issues to edit other users descriptions. Issue can be created with read access.

We may have to specify zhis in future ... (spam protection & co ...)

@brunoais It's not intuitive, but "read" permissions include creating issues and editing/closing own issues. "Write" permissions include modifying/closing issues from other users.

[brunoais]

Thank you @lafriks & @guillep2k . It is really not intuitive... I think I'm giving too many permissions to my users, then...

[lafriks]

@brunoais that how it was also before and also same as it is for github

[lafriks]

If you need for users only to be able to create issues and update their own, just set them read rights for issues

[brunoais]

Used github a lot. Never managed accounts on github (I never owned any repo without it being a clone an/or public repo)

[guillep2k]

I think we should improve the way the permissions for groups are presented in the UI.
