29 | * Modified 28/11/2001 Iustin Pop <iusty@intensit.de> |
30 | * There was a bug regarding the LDAP_TLS option: if both LDAP_TLS |
31 | * and was LDAP_AUTHBIND were enabled, the ldap_start_tls function |
32 | * was called only for the first connection, resulting in the fact |
33 | * that the bind for checking the password was done without TLS, |
34 | * sending the password in clear text over the network. Detected |
35 | * when using OpenLDAP with "security ssf=128" (which disalows any |
36 | * clear-text communication). |

40 | Modified 01/21/2000 James Golovich <james@wwnet.net> |
41 | |
42 | 1. If LDAP_AUTHBIND is set in the config file, then the ldap server will |
43 | handle passwords via authenticated binds, instead of checking these |
44 | internally. |
45 | 2. Changed paramaters for authldap_get to include pass. |

49 | /* |
50 | Modified 12/31/99 Sam Varshavchik: |
51 | |
52 | 1. read_env reads from a configuration file, instead of the environment |
53 | 2. read_config appropriately modified. |
54 | 3. If 'user' contains the @ character, domain from config is NOT appended. |
55 | 4. added 'homeDir' attribute. Use 'homeDir' instead of mailDir, and put |
56 | mailDir into MAILDIR= |
57 | 5. read_config renamed to authldap_read_config |
58 | 6. get_user_info renamed to authldap_get |
59 | 7. Added authldap_free_config, to clean up all the allocated memory |
60 | (required for preauthldap). |
61 | 8. Output LDAP attributes are defined in the configuration file as well. |
62 | 9. Allow both plaintext and crypted passwords to be read from LDAP. |
63 | 10. Added GLOB_UID GLOB_GID, as well as UID and GID params. |
64 | |
65 | 2/19/2000 Sam. |
66 | |
67 | Rewrite to allow this code to be used in a long-running authentication daemon |
68 | (for Courier). authldap_get renamed to authldapcommon, will initialize and |
69 | maintain a persistent connection. Password checking moved entirely to |
70 | authldap.c. authldapclose() will unbind and close the connection. |
71 | |
72 | connection gets closed and reopened automatically after a protocol error. |
73 | |
74 | error return from authldapcommon will indicate whether this is a transient, |
75 | or a permanent failure. |
76 | |
77 | authldap_free_config removed - no longer required. |
