Yeah, _our_ mod_become swaps between user ids. If the standard mod_become does not do that, than our sysadm coded that. (I'm unclear what he did exactly). But we have it running on our production machine now, without any problems.
could you please explaing how a process is able to change its user id at will? afaik only root is allowed to change the user id and there is no way back (for a reason) and if there was a way to do so, how would you prevent a certain piece of code to do so while you allow it for another piece of code in the same process? -- Hartmut Holzgraefe hartmut@six.de http://www.six.de +49-711-99091-77
