Description Dmitri Pal 2012-08-02 13:26:56 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/1451

In the "ID MAPPING" section of the manpage, the ldap_idmap_range_size should have a mention that the value should be atleast the user's corresponding RID on the AD Server.

e.g. for a user with objectSid=S-1-5-21-2153326666-2176343378-3404031434-1107,  ldap_idmap_range_size should be atleast 1107. Lookups/enumeration for the user will not work if a value less than that is mentioned.

Comment 5 Kaushik Banerjee 2015-01-05 10:32:40 UTC

Verified in version sssd-1.12.2-39.el7


sssd-ad manpage has:

NOTE: The value of this option must be at least as large as the
highest user RID planned for use on the Active Directory
server. User lookups and login will fail for any user whose RID
is greater than this value.

For example, if your most recently-added Active Directory user
has objectSid=S-1-5-21-2153326666-2176343378-3404031434-1107,
“ldap_idmap_range_size” must be at least 1107.

It is important to plan ahead for future expansion, as changing
this value will result in changing all of the ID mappings on
the system, leading to users with different local IDs than they
previously had.
