I have been unable to enable plain authorization from SuSE 10.0's LDAP server. The /etc/openldap/slapd.conf file contains the required: security ssf=0 sasl-secprops none However, despite this: linux:~ # ldapsearch -v -x -s base -b "" supportedSASLMechanisms ldap_initialize( <DEFAULT> ) filter: (objectclass=*) requesting: supportedSASLMechanisms # extended LDIF # # LDAPv3 # base <> with scope base # filter: (objectclass=*) # requesting: supportedSASLMechanisms # # dn: supportedSASLMechanisms: DIGEST-MD5 supportedSASLMechanisms: CRAM-MD5 # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 What else must I do in order to enable the required PLAIN authorization (which should have been listed above with DIGEST-MD5 and CRAM-MD5)? ANONYMOUS should also have been there.
