Re: [HTCondor-users] write and execute from different computer in grid

[Renà Labounek <xlabou01@xxxxxxxxxxxxxxxxxx>]

I think I have found a problem. Based on chapter 2.5.3 in next URL, UIDs 
and GIDs must agree between computers. and they are not. Even not for 
the condor user. Can I manually rewrite uid and gid for condor user on 
one computer without breaking the HTcondor installation?
