Dear experts,

in a testing environment (SLES 15 SP5, OpenLDAP 2.5.14) I use the following ACLs in olcAccess:

{0}to dn.exact="cn=test,ou=users,dc=foo,dc=bar" by dn.exact="cn=test,ou=users,dc=foo,dc=bar" peername.ip="10.10.10.10" write by * none {1}to * by group.exact="cn=Admins,ou=groups,dc=foo,dc=bar" manage by * none break {2}to * by self read by anonymous auth by * none break

If I run ldapmodify -xWD "cn=test,ou=users,dc=foo,dc=bar" to change the account cn=test,ou=users,dc=foo,dc=bar on the system with ip 10.10.10.10 everything works as expected.

LDAP-Log: 2023-06-16T12:53:12.024030+02:00 tst1 slapd[1333]: conn=1016 fd=28 ACCEPT from IP=10.10.10.10:53558 (IP=0.0.0.0:636) 2023-06-16T12:53:12.039643+02:00 tst1 slapd[1333]: conn=1016 fd=28 TLS established tls_ssf=128 ssf=128 tls_proto=TLSv1.3 tls_cipher=TLS_AES_128_GCM_SHA256 2023-06-16T12:53:12.039773+02:00 tst1 slapd[1333]: conn=1016 op=0 BIND dn="cn=test,ou=users,dc=foo,dc=bar" method=128 2023-06-16T12:53:12.039841+02:00 tst1 slapd[1333]: conn=1016 op=0 BIND dn="cn=test,ou=users,dc=foo,dc=bar" mech=SIMPLE bind_ssf=0 ssf=128 2023-06-16T12:53:12.041918+02:00 tst1 slapd[1333]: conn=1016 op=0 RESULT tag=97 err=0 qtime=0.000014 etime=0.002242 text= 2023-06-16T12:53:30.488074+02:00 tst1 slapd[1333]: conn=1016 op=1 MOD dn="cn=test,ou=users,dc=foo,dc=bar" 2023-06-16T12:53:30.488474+02:00 tst1 slapd[1333]: conn=1016 op=1 MOD attr=description 2023-06-16T12:53:30.557458+02:00 tst1 slapd[1333]: conn=1016 op=1 RESULT tag=103 err=0 qtime=0.000022 etime=0.069664 text= 2023-06-16T12:53:33.035486+02:00 tst1 slapd[1333]: conn=1016 fd=28 closed (connection lost)

Running the above command from another machine results in a Insufficient access (50) error as also expected. So I assume the ACLs to be working correctly.

If I run slapacl -F /etc/symas/etc/openldap/slapd.d -o peername=10.10.10.10 -D cn=test,ou=users,dc=foo,dc=bar -b cn=test,ou=users,dc=foo,dc=bar on the system with ip 10.10.10.10 I get the following output:

I expected to see write access in slapacl's output.

If I remove the 'peername.ip="10.10.10.10"' part from olcAccess {0}to dn.exact="cn=test,ou=users,dc=foo,dc=bar" by dn.exact="cn=test,ou=users,dc=foo,dc=bar" peername.ip="10.10.10.10" write by * none the above slapacl command outputs write access correctly no matter if the parameter '-o peername=10.10.10.10' is set or not.

Am I doing something wrong? Any help is appreciated.
