Reconcile issue with previously synced group no more available

[yurifrancalacci]

Hi all,
here follows the scenario I have with this issue.

• (Ldap) Configuration with whitelist in sync regularly and no issue

then:

• a previously synced group is renamed in ldap
• the "new" group is added to groupsync whitelist without removing the "old" name
  this caused a reconcile error and sync is stopped for all the whitelisted groups

operator version 0.0.28
here is a log snippet
1.7176737338123524e+09 ERROR syncer_ldap Error building OpenShift group for LDAP group {"LDAP Group UID": "CN=xxxxx,OU=yyyyy,OU=zzzz,DC=kkk,DC=ttt", "error": "search for entry with base dn="OU=yyyyy,OU=zzzz,DC=kkk,DC=ttt" and filter "(&((&(objectClass=group)(memberOf:1.2.840.113556.1.4.1941:=OU=yyyyy,OU=zzzz,DC=kkk,DC=ttt)))(distinguishedName=CN=xxxxxxx,OU=yyyyy,OU=zzzz,DC=kkk,DC=ttt))" did not return any results"}
