Migrated CVS to new server - why did the file commit with a weird, non-cvs, group name?

We just migrated a cvs file repository from one server to another. To test it out, I checked out, changed, then committed a file. The owner / group changed from "cvs / cvs" to "MyAccount / SomeoneElseAccount". I was expecting at least "MyAccount / cvs". 1. What was I supposed to expect? 2. Do I need to resolve this, or is this OK? 3. How might I resolve this if it is not OK? UPDATE Per the comments, I checked user ids. Results on same line after '='. id -u cvs = 60000 id -g cvs = 60000 id -G cvs = 600000 20 40 id -u MyAccount = 200007 id -g MyAccount = 200002 id -G MyAccount = 200002 60000 100005 100025 id -u SomeoneElseAccount = 200002 id -g SomeoneElseAccount = 200002 id -G SomeoneElseAccount = 200002 100678 I also had "AnotherUser" check out and commit; his file also ended up with group "SomeoneElseAccount". id -u AnotherUser = 200018 id -g AnotherUser = 200002 id -G AnotherUser = 200002 60000 100005 100025 Setup on the old server provides a similar id configuration with 200002, though cvs is '100' there, and the items are committed as group 'cvs'. Checking /etc/group OLD SERVER cat /etc/group ... cvs:!:200002:name,name,name,MyAccount,AnotherUser,name,name... ... NEW SERVER cat /etc/group ... cvs:!:60000:name,name,name,MyAccount,AnotherUser,name,name... ...
