Hello all,
I was wondering if there was a sane way of working out username given a
numeric user id during the RCPT TO ACL. There are plenty of ways to do
it vice versa (passwd db lookup, lsearch /etc/passwd).
So far I've come up with either using perl, or running a command. So
I've got:
-----------8<-----------------------
# This variable contains the user ID of the owner of the vhost directory
set acl_m0 = ${extract{uid}{${stat:/home/${domain}}}}
# This variable then contains the username (or nobody if grep fails, or the
# userid < 1000)
set acl_m1 = ${if <{1000}{$acl_m0}{nobody}\
{${extract{1}{:}\
{${run{ \
/bin/egrep "^[^:]+:[^:]+:$acl_m0:" /etc/passwd\
}{$value}{nobody}}}\
}}\
}
-----------8<-----------------------
which is OK, but not great. I'd much rather have
-----------8<-----------------------
set acl_m0 = ${extract{username}{\
${lookup getpwid{\
${extract{uid}{${stat:/home/${domain}}}}
}} \
}}
-----------8<-----------------------
which is marginally neater. Having had a look at lookup/passwd.c in the
source, I fear patching the code!
Thanks!
