hi, thx for your patience...
>>Okay, I'm a little confused now
*sorry, sorry for my bad english...
>>You have an NIS master and an NIS slave. Host server1 is an NIS client bound to the NIS slave?
*yes, server1 is bind to nisslave1( and every other slaves work fine )
>>I think you said that ypcat group on server1 shows the correct data. Is this true?
*yes, it is surprising, but i think correct data come from passwd.byname or group.byname, i think i have a synchronisation Pb with group.bygid and passwd.byuid.
>>what makes you think the group map is not getting updated. On which machine is ypcat failing to show the correct info?
* i have a user1 in group1(GID=100) (this group exists for a long time)
i have a user2 in group2(GID=200) (this group is a newly created group)
on the server1
when i create a file with user1, the file owner is user1 group1
when i create a file with user2, the file owner is user2 200
on a server2 which binds to an other nis slave ( nisslave2) the owner is
user1 group 1 & user2 group2
and on nisslave2 the synchronisation is ok...
that's why i think it could be a nis probleme.
