Issue ID: 10048 Summary: adding a regex entry for overlay variant crashes slapd Product: OpenLDAP Version: 2.6.4 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs@openldap.org Reporter: stefan@kania-online.de Target Milestone: ---

I'm using symas-packages 2.6.4 on a Debian 11 system. Two providers with multi provider replication.

I try to add different entries wit overlay "variant" first without regex. Here my ldif for the configuration: ----------- dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: variant.la ----------- ----------- dn: olcOverlay={2}variant,olcDatabase={2}mdb,cn=config objectClass: olcVariantConfig olcVariantPassReplication: TRUE

dn: name=global-addr,olcOverlay={2}variant,olcDatabase={2}mdb,cn=config objectClass: olcVariantVariant olcVariantEntry: dc=example,dc=net

dn: olcVariantVariantAttribute=postaladdress,name={0}global-addr,olcOverlay={2}variant,olcDatabase={2}mdb,cn=config objectClass: olcVariantAttribute olcVariantVariantAttribute: postaladdress olcVariantAlternativeAttribute: postaladdress olcVariantAlternativeEntry: ou=firma,dc=example,dc=net

dn: name=company-phone,name={0}global-addr,olcOverlay={2}variant,olcDatabase={2}mdb,cn=config objectClass: olcVariantAttribute olcVariantVariantAttribute: telephonenumber olcVariantAlternativeAttribute: mobile olcVariantAlternativeEntry: cn=verw-al,ou=users,ou=verwaltung,ou=firma,dc=example,dc=net ----------- That works as expected.

Then I wrote a ldif-file for variant WITH regex: ----------- dn: name=verw-tel,olcOverlay={2}variant,olcDatabase={2}mdb,cn=config objectClass: olcVariantRegex olcVariantEntryRegex: cn=.+,ou=users,ou=verwaltung,ou=firma,dc=example,dc=net

dn: olcVariantVariantAttribute=telephonNumber,name={1}verw-tel,olcOverlay={2}variant,olcDatabase={2}mdb,cn=config objectClass: olcVariantAttributePattern olcVariantVariantAttribute: telephoneNumber olcVariantAlternativeAttribute: telephoneNumber olcVariantAlternativeEntryPattern: ou=Verwaltung,ou=firma,dc=example,dc=net ----------- When I try to add the ldif with ldapadd slapd crashes with the following messages in the log: --------------- May 06 08:16:28 provider02 slapd[8018]: conn=1001 fd=20 ACCEPT from PATH=/var/symas/run/ldapi (PATH=/var/symas/run/ldapi) May 06 08:16:28 provider02 slapd[8018]: conn=1001 op=0 BIND dn="" method=163 May 06 08:16:28 provider02 slapd[8018]: conn=1001 op=0 BIND authcid="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" authzid="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" May 06 08:16:28 provider02 slapd[8018]: conn=1001 op=0 BIND dn="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" mech=EXTERNAL bind_ssf=0 ssf=71 May 06 08:16:28 provider02 slapd[8018]: conn=1001 op=0 RESULT tag=97 err=0 qtime=0.000009 etime=0.000146 text= May 06 08:16:28 provider02 slapd[8018]: conn=1001 op=1 ADD dn="name=verw-tel,olcOverlay={2}variant,olcDatabase={2}mdb,cn=config" May 06 08:16:28 provider02 slapd[8018]: slap_get_csn: conn=1001 op=1 generated new csn=20230506081628.055320Z#000000#001#000000 manage=1 May 06 08:16:28 provider02 slapd[8018]: slap_queue_csn: queueing 0x7f7c64012890 20230506081628.055320Z#000000#001#000000 May 06 08:16:28 provider02 slapd[8018]: olcVariantEntryRegex: value #0: <olcVariantEntryRegex> handler exited with 19!
