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

Reporter: [email protected]
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:

---------------
Even if olcVariantEntryRegex is wrong (what I don't know up to now) slapd
should not crash.
