Hi, I'm trying to add an 'olcAttributeType' to an already existing LDAP schema. I wrote this LDIF, which was wrong as it turns out: | dn: cn=schema,cn=config | changetype: modify | add: olcAttributetypes | olcAttributetypes: ( bitHttpAttribute:26.2008.07.29.1 NAME | 'testEntry' DESC 'Test' EQUALITY integerMatch SYNTAX | LDAPInteger SINGLE-VALUE ) This changed my 'dn: cn=schema,cn=config' from: | dn: cn=schema,cn=config | objectClass: olcSchemaConfig | cn: schema | structuralObjectClass: olcSchemaConfig | entryUUID: 9faa0e66-41f5-1032-82e1-974d55020d34 | creatorsName: cn=config | createTimestamp: 20130425131311Z | entryCSN: 20130425131311.204787Z#000000#000#000000 | modifiersName: cn=config | modifyTimestamp: 20130425131311Z To: | dn: cn=schema,cn=config | objectClass: olcSchemaConfig | cn: schema | structuralObjectClass: olcSchemaConfig | entryUUID: 9faa0e66-41f5-1032-82e1-974d55020d34 | creatorsName: cn=config | createTimestamp: 20130425131311Z | olcAttributeTypes: {0}( bitHttpAttribute:26.2008.07.29.1 NAME | 'testEntry' DESC 'Test' EQUALITY integerMatch SYNTAX | LDAPInteger SINGLE-VALUE ) | entryCSN: 20220525132055.795116Z#000000#000#000000 | modifiersName: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth | modifyTimestamp: 20220525132055Z Which is not what i wanted but it happened, so now i want it gone. But it seems i can't remove that olcAttributeTypes entry? This LDIF won't work: | dn: cn=schema,cn=config | changetype: modify | delete: olcAttributeTypes Yielding: | # ldapmodify -Y EXTERNAL -H ldapi:/// -f kak.ldif | [..] | modifying entry "cn=schema,cn=config" | ldap_modify: Other (e.g., implementation specific) error (80) When i put in the exact olcAttributeType line i want to remove (instead of all of 'em) like this: | dn: cn=schema,cn=config | changetype: modify | delete: olcAttributeTypes | olcAttributeTypes: ( bitHttpAttribute:26.2008.07.29.1 NAME 'testEntry' DESC 'Test' EQUALITY integerMatch SYNTAX LDAPInteger SINGLE-VALUE ) Now the same ldapmodify command yields: | # ldapmodify -Y EXTERNAL -H ldapi:/// -f kak.ldif | [..] | modifying entry "cn=schema,cn=config" | ldap_modify: Operations error (1) Can anyone explain what i am doing wrong and how to revert my change to the 'cn=schema,cn=config' dn? Thanks a bunch! Regards, -Sander. -- | I did a theatrical performance about puns. It was a play on words. | 4096R/20CC6CD2 - 6D40 1A20 B9AA 87D4 84C7 FBD6 F3A9 9442 20CC 6CD2
