zenrestore Access denied for user 'zenoss'@'localhost' followed by more grief

We have an existing ZenOss machine running on RHEL 5 32-bit, I wanted to bring up a dev machine for testing upgrades, used same arch same OS and installed the same version (2.5.2) of Core, added in same ZenPacks and made sure everything was matching the production machine.


I did a backup and copied the largish (782 MB) file over to the dev box and did (as zenoss user) like follows:

$ zenrestore --file zenbackup_20110629.tgz

ERROR 1045 (28000): Access denied for user 'zenoss'@'localhost' (using password: YES)

Curious about what's going on with the DB, I did a zendmd, or tried to:

$ /opt/zenoss/bin/zendmd

Google showed me a couple of other cases where people were having such troubles, but they were all trying to do a zenrestore onto a 64-bit platform from a 32-bit-generated backup.  Since that's not the case here, what else could be causing this grief and more importantly how can it be fixed?
