Description Scott Balmos 2005-02-10 23:20:17 UTC
The port of amavisd-new (security/amavisd-new) creates a user account and group, vscan/vscan, for Amavis to run under. However, the command to pw which creates the account does not specify a UID. Thus, the account is created using the next available normal user uid, not with a uid normally reserved in the "system account" space (uid/gid <1000). This can be annoying to systems set up with user account managers that do not use pw and /etc/master.password, and are shared across multiple servers (e.g. LDAP). vscan on one box could be 1002, on another box could be 1010, etc, depending on how many regular user accounts were created before the amavisd-new port was installed.

It would be better if the vscan user was created using an explicit "system account" uid/gid, such as uid/gid 102 (which doesn't seem to be used by any port that I know of).

Fix: Explicitly assign uid/gid 102 to vscan.
How-To-Repeat: Load a fresh FreeBSD box. Create a few normal user accounts (e.g. ones that are auto-assigned uid's, incrementing starting from uid 1000).

Install security/amavisd-new somewhere along the line.

pw usershow vscan and pw groupshow vscan. Note they are also given auto-assigned uid's.

Oops... Mistake here. Didn't check Sect. 17.12 of the Porter's Handbook 
first. :(

New suggested uid/gid: 110

Approved. Don't forget to reserve the UIDs in the porters handbook and to 
increase the portrevision.
