Hi,=0A= =0A= The NFSv4 RFCs do not specify an upper limit for the length=0A= of a user or group (called Owner/Owner_group in NFSv4) string.=0A= =0A= However, PR#260546 notes that a sanity upper limit for their=0A= length is needed.=0A= =0A= Is there any constant in FreeBSD that defines the upper limit for=0A= the length of a user or group name?=0A= (I can find the maximum length of a hostname and I think that can=0A= be used as a safe upper limit for a domain name, as well. The Owner/=0A= Owner_group names include "@domain" on them.)=0A= =0A= Thanks for any help with this, rick=0A=
