Full_Name: Manny Version: 2.4.23 OS: RHEL6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (193.171.77.1) Hi there. I'm posting this into the ITS as I didn't get a response on the mailing list after 1 week. I'm using the latest stable release of openldap, with back-sql and postgresql as a backend. I have an sssd which uses this openldap server for ID providing and authentication. A recent update in this sssd changed the filter used to retrieve groupids of users, which surfaced what seems to be a bug in backsql. >From my investigation it seems to me that when constructing the search query, openldap tries to use the UPPER function on every criteria in the WHERE clause, no matter which type it is. This causes an error in postgresql, as the gidNumber that is supposed to be filtered is of type "bigint".
