.xsession in xdm session

[Paulo Henrique Baptista de Oliveira]

        Hi all,
        I installed a Debian Linux Sun Port in a Sparc 4 here at school, but
some people have a .xsession file that is not executable because they use
Solaris and some program set this file. But they cant log in xdm because xdm
found the .xsession file but cant execute it.
        The question is what is the better solution to this problem?
        chmod +x ~accounts/.xsession
        or in some /etc/X11/* file put: sh .xsession
        Thanks,         Paulo Henrique
