Hello, We've got a strange problem: I'll explan: the directory prod contains: total 32 drwxrwxr-x 3 roos swgis 512 May 29 11:48 . drwxrwxrwx 3 root system 512 May 29 10:19 .. -rw-rw-r-- 1 marcel swgis 7 May 29 11:48 marcel_test.magik drwxrwxr-x 4 roos swgis 512 May 29 11:39 tools user marcel can create and write a (new) file in the prod dir, as it should. When he query's the directory prod if het can write to this directory he gets a false from his application although he is from group swgis. When I set the permissions of prod to rwxrwxrwx then he gets a true from his application. It seems to me that although he is connected as id=marcel and gid=swgis the query to access the directoy is not done by marcel or root ??? If anybody can shed some light on this, I'll be gratefull. greetings, Richard.
