Subject: sidgen: ignore staged users when generating SIDs
|
|
|
|
|
|
Staged users have
|
|
|
|
uidNumber: -1
|
|
gidNumber: -1
|
|
ipaUniqueID: autogenerate
|
|
|
|
We cannot generate ipaSecurityIdentifier based on those UID/GID numbers.
|
|
However, '-1' value will trigger an error
|
|
|
|
find_sid_for_ldap_entry - [file ipa_sidgen_common.c, line 483]: ID value too large.
|
|
|
|
And that, in turn, will cause stopping SID generation for all users.
|
|
|
|
Detect 'ipaUniqueID: autogenerate' situation and ignore these entries.
|
|
