Hi,
We are pulling certificate as it is required in our client applications using Gluu. We did try the objectGuid approach mentioned in the [link ](https://gluu.org/docs/integrate/office365/)in your earlier apply. But still we are facing issue.
```
[org.gluu.site.ldap.OperationsFacade] (pool-4-thread-7) Entry can't be modified
LDAPException(resultCode=21 (invalid attribute syntax), errorMessage='When attempting to modify entry inum=@!5863.FE5A.5F3C.E87D!0001!8E7C.A82D!0000!B043.B1E0,ou=people,o=@!5863.FE5A.5F3C.E87D!0001!8E7C.A82D,o=gluu, one value for attribute userCertificate was found to be invalid according to the associated syntax: The provided value is not a valid X.509 Certificate: org.forgerock.opendj.ldap.DecodeException: Cannot decode the ASN.1 element because it contained a multi-byte length with an invalid number of bytes (111)', diagnosticMessage='When attempting to modify entry inum=@!5863.FE5A.5F3C.E87D!0001!8E7C.A82D!0000!B043.B1E0,ou=people,o=@!5863.FE5A.5F3C.E87D!0001!8E7C.A82D,o=gluu, one value for attribute userCertificate was found to be invalid according to the associated syntax: The provided value is not a valid X.509 Certificate: org.forgerock.opendj.ldap.DecodeException: Cannot decode the ASN.1 element because it contained a multi-byte length with an invalid number of bytes (111)')
