I have the following problem with nfs:
Server A exports a directory via nfs to client B. User and group informations are stored in LDAP. The exported directory has mode 770.
Tests:
Server: If I'm the owner of the directory or belong to the group, I can create new files or change the content of the file.
-> No problems
Client: No problems, if I'm the owner of the directory. But if I'm not the owner, I could create new files because I belong to the group. This doesn't work. I've only got a "permission denied". If I create the group on the client with the users, I can create new files, too.
So it seems that write requests don't propperly resolve the group permissions if the group is a LDAP group and the directory is exported by an NFS server. ls and "getent group" are showing correct group names, permissions and group users. The r-bit is correctly working, too.
So where is the bug? The nfs kernel server? Within the kernel?
Debian testing on both machines. nfs-kernel-server: 1:1.0.6-1 linux kernel: 2.4.21 'til 2.4.23
Shade and sweet water!
