On 2.4.X i didnt have any issues using rsyslog with "local4.* /var/log/slapd/slapd.log" and I would get all the connection and searches done on the db. Which was great!!

I am having a hard time doing the same thing with 2.5.7.

Without any changes to the service file, just running slapd on rocky linux 8 i get these logs on /var/log/slapd/slapd.log only

Sep 23 10:10:18 localhost slapd[3992243]: @(#) $OpenLDAP: slapd 2.5.7 (Aug 19 2021 17:48:53) $#012#011mockbuild@3b6af787015541c89363999d4338d587:/builddir/build/BUILD/openldap-2.5.7/servers/slapd

If i change the service file with (-d 256):
ExecStart=/opt/symas/lib/slapd -d 256 -h ${SLAPD_URLS} $SLAPD_OPTIONS

I get at least these msgs:

614c8ac4.0dc359b2 0x7fdf0f91f700 conn=1000 fd=17 ACCEPT from IP=[xxxx]:55556 (IP=[xxxx]:389)

But unfortunately I do not get them to log into my slapd.log file.
I even added -l local4 but no change.
Is (-d 256) even correct?

/opt/symas/lib/slapd -d ?
