Is webdev in the local gtroup mapping table ?

yes.  But there's some missing details in your original post.
Sounds like your server is configured as a domain member server.
is the user logging as a domain user ?  Or a local user?

The domain user will only get domain groups (and possible
local nested groups from winbindd) unless you explicitly
map the domain\user account to a specific local Unix account.
