opendirectorysam.so error

I'm trying to create a two way domain trust between an XServe (domain "mac") and a Windows NT4 style domain (domain "lab"). I created a machine account lab$ in WGM as articles suggest. [code:1:199ca668a0]net rpc trustdom establish lab [/code:1:199ca668a0] worked fine though the trust itself doesn't work. [code:1:199ca668a0]smbpasswd +a +i lab[/code:1:199ca668a0] yields: [code:1:199ca668a0]/etc/pdb/opendirectorysam.so undefined reference to _get_opendirectory_authenticator expected to be defined in the executeable. Trace/BPT trap[/code:1:199ca668a0] Anyone know of a fix for this issue?
