Hi list
we have some problems with our group mappings.
Users of the group domainusers cannot access a share where this
group has access rights. Usually to increase the upper values
of the idmap range helps for some time.
In the case of the error the winbindd-idmap log is full of:
Fatal Error: GID range full!! (max: 300000)
Someone in the samba bug reports some time ago was told to use
net idmap check.
I did aswell:
check database: /var/lib/samba/winbindd_idmap.tdb
Invalid USER HWM 12024: should be 1
Invalid GROUP HWM 300001: should be 177125
uid hwm: 0
gid hwm: 177124
mappings: 6
other: 3
invalid records: 0
missing links: 0
invalid links: 0
There is the option to repair the database by using
net idmap check -r
but is this save? What happens when the USER HWM is set back to 1.
We are using samba 3.6.6 (debian stable backports)
Output from smb.conf:
# ldap settings
passdb backend = ldapsam
ldap suffix = dc=ourdomain,dc=de
ldap admin dn = cn=samba,dc=ourdomain,dc=de
ldap user suffix = ou=users
ldap group suffix = ou=groups
ldap machine suffix = ou=computers
ldap idmap suffix = ou=idmaps
ldap ssl = no
ldapsam:trusted = yes
ldapsam:editposix = yes
# winbind settings
idmap config * : range = 12000 - 300000
Thanks for your help
Sebastian
