Subject: [PATCH] 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.
Fixes: https://pagure.io/freeipa/issue/9517
