[Samba] RE: Solaris NSS/winbind problem - large groups

[Hutching, Kevin]

Does anyone know if this is a problem specific to Solaris or if there is an
existing fix or one on the way? Any help is greatly appreciated.

'getent group "Domain Users"' (or any other large group) 	-hangs
'getent group' 	-does not return a full group listing.
'wbinfo -g' 	-lists all groups

partial truss output of getent group "Domain Users" (Repeats):

In a previous list in samba-technical from last year, Andrew Bartlett wrote:
"From what I understand, the issue is not in winbindd, or wbinfo - but in
nss_winbindd. So the command to run under truss is 'id' or 'getent group'
etc. This is why I think this is a solaris specific sun (or
winbind_nss_solaris.c) bug. Andrew Bartlett"
