All of the BSD interfaces, including glibc's own implementation of getpw return -1 and set errno to 0 to indicate that there was no user corresponding to that uid. I have never under any condition seen an NSS backend return ENOENT via the set of APIs that getpw uses internally in glibc. Therefore I would suggest the manual page be expanded to include 0 in the list of valid errno values that indicate no corresponding user. I reorganize the list of errors to have the non-error at the top, as is done with getgrnam.3 and getpwnam.3 which have similar behaviour in the non-error case.
