We recently upgrade Gluu on EKS from version 4.0 to 4.1, using the steps in the Gluu CE 4.1 documentation
After the upgrade, we could no longer update the Cache Refresh configuration. Any updates to the config will be reverted to the original values. The cr-rotate pod does not update the cache refresh info either. After troubleshooting with Mohammad Abudayyeh, we discovered that the ldap did not update with the error in oxtrust.log and also in ldapbrowsers:
```Caused by: com.unboundid.ldap.sdk.LDAPException: Entry ou=configuration,o=gluu cannot be modified because the resulting entry would have violated the server schema: Entry ou=configuration,o=gluu violates the Directory Server schema configuration because it includes attribute gluuPersonCount which is not allowed by any of the objectclasses defined in that entry
The ou=configuration,o=gluu was missing the `gluuOxtrustStat` objectclass and therefore oxtrust could not update the ldap entry.
Can you kindly assist in looking into this issue and possibly the upgrade steps also.
