My organization has made extensive use of the Directory Server (Web) Gateway (DSGW) for 20 years. I've yet to come across any suitable alternative (suggestions welcome if you're familiar with its functionality).

We are at least a decade behind with updates, having been tied to the Oracle fork of directory and mail server products until recently. I am now experimenting with potential conversion to 389-DS or RHDS including the updated DSGW, and I may have encountered a bug.

Is the DSGW still used and supported?

The specific problem appears to be the edit command (/usr/lib64/dirsrv/dsgw-cgi-bin/edit) failing to handle "syntax=mls" as encountered in a template file (/usr/share/dirsrv/dsgw/config/display-orgperson.html). The problem occurs if the attribute involved exists in the entry being edited, whether its value contains multiple lines or not.

The symptom: The multi-line data is displayed cleanly using the search or csearch commands, but upon clicking the Edit button to enter edit mode, the web form is truncated. Bottom half blank, from one cell above whatever cell contains "syntax=mls". In the distributed template file the trigger line is:
<!-- DS_ATTRIBUTE "attr=postalAddress" "syntax=mls" "type=TEXTAREA" "cols=>40" "rows=>4" -->

The test environment:
