struct idmap_context contains configuration data (struct idmap_config), a cache for users, and a cache for groups. idmap_context is declared in idmap.c, and only available as an opaque pointer (nfs41_idmapper) elsewhere. similarly, Winldap.h is only included by idmap.c, and not needed elsewhere nfs41_idmap_create() allocates the idmap_context, loads the configuration from file, and calls ldap_init(). it does not call ldap_connect(); we'll still be able to start the daemon if ldap isn't configured, or the ldap server is down. calling ldap_connect() is optional, as any ldap operation that requires a connection will establish it internally. this behavior, along with the LDAP_OPT_AUTO_RECONNECT option (defaults to on), means that we shouldn't have to maintain a separate connection for each thread nfs41_idmap_*() functions return windows errors codes. LDAP_RETCODEs are mapped to windows errors with LdapMapErrorToWin32() the user and group caches share a common generic interface in struct idmap_cache, which uses a linked list for storage, and protects access with a SRWLOCK. expiration of cache entries can be adjusted by the config option 'cache_ttl' struct config_option g_options[] is a table of available config options and their default values. this patch adds a 'ms-nfs41-idmap.conf' file with all possible options set to default values, and commented out. the daemon expects to find this file under c:\etc\, and won't start if it can't be opened or parsed Signed-off-by: Casey Bodley <cbodley@citi.umich.edu>
