well, it does a loop asking the OS if the uid/gid is available until it finds one that should be available (see pextlib1.0/Pextlib.c line 242)

So, there was already an OD account with ID 1026 (or did you try to set up your wife's account later, and that failed?)

I _think_ getpwuid() should pull in the information from OD (and maybe there's a lion change/bug that is causing the issue?). Certainly the manpage on 10.6 says "These functions obtain information from DirectoryService(8)"

I think we probably should figure out why the OD accounts (and groups?) aren't seen by base/ when it's looking for the next available UID/GID
