Update.
* grp/initgroups.c (initgroups): Don't limit the possible number of groups to NGROUPS_MAX. Allow dynamic resizing. Loop around the setgroups call while the call fails and descrease the number of groups each round. The name of the initgroups function in the NSS modules changed. (compat_call): Adapt for dynamic resizing. * hesiod/nss_hesiod/hesiod-grp.c (_nss_hesiod_initgroups_dyn): Implement dynamic resizing. * nis/nss_compat/compat-initgroups.c (_nss_compat_initgroups_dyn): Likewise. * nis/nss_nis/compat-initgroups.c (_nss_nis_initgroups_dyn): Likewise. * hesiod/Versions: Change exported interface name. * nis/Versions: Change exported interface name. 2000-07-23 Ulrich Drepper <drepper@redhat.com>
