I didn't run mergemaster because didn't say to.
However, I did try su at the console with the same result, but I was
getting pam_acct_mgmt: authentication errors. I checked
/etc/master.passwd and noticed that the accounts I was trying to su to
were locked. I tried "passwd account" as root on an account that
wasn't working and once I set a password it I could su to it as long
as logins were enabled. I tried another account with disabled logins
and got "This account is currently not available".

Both of these accounts only exist to let servers run as different
users. What's the proper way to set them up? Maybe that's my issue
instead. I only noticed this because the servers weren't starting
because the init scripts can't su to the right users anymore.
