Description of problem: Users created at DS with a comma in the CN entry fails to sync to AD. 


Version-Release number of selected component (if applicable): DS90


How reproducible: Consistently


Steps to Reproduce:
1. Setup windows sync with win2008 AD server.
2. Create few entries at DS and AD before running "Initiate Full Re-synchronization".
3. Create entries in DS as this ldif file.

dn: uid=testwinsyncsplDN\2C1,dc=pass_sync,dc=com
telephoneNumber: 989898191
mail: testwinsyncsplDN1
givenName: testwinsyncsplDN1
objectClass: top
objectClass: person
objectClass: inetorgperson
objectclass: ntUser
sn: testwinsyncsplDN,1
cn: testwinsyncsplDN,1
ntUserCreateNewAccount: true
ntUserDomainId: testwinsyncsplDN1
ntUserDeleteAccount: true
userPassword: Secret1234

4. User successfully added to DS.
5. Run ldapsearch to check whether the entries are created at AD.
6. Check the error logs.  

Actual results:
Entries fail to Sync to AD and this affects the other entries valid entries to be synced.

Error log says, its a DN syntax error.

[27/Jul/2011:08:50:37 -0400] NSMMReplicationPlugin - agmt="cn=WinPassSyncPAMAD" (win2k8rhvd64:636): process_replay_add: failed to create mapped entry dn="cn=testwinsyncsplDN,1,ou=pass_sync,dc=win2k8sync64,dc=com"
[27/Jul/2011:08:50:37 -0400] NSMMReplicationPlugin - Could not retrieve entry from Windows using search base [cn=testwinsyncsplDN,1,ou=pass_sync,dc=win2k8sync64,dc=com] scope [0] filter [(objectclass=*)]: error 34:Invalid DN syntax



Expected results:
The entry should be synced to AD as comma is allowed in the CN's entry.

Additional info:

I tried adding a new user at AD as this ldif, and it fails with DN syntax error.

dn: CN=testADUsr,_1,OU=pass_sync,DC=win2k8sync64,DC=com
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: user
cn: testADUsr,_1
sn: testADUsr,_1
uid: testADUsr,_1
givenName: testADUsr_1
distinguishedName: CN=testADUsr_1,OU=pass_sync,DC=win2k8sync64,DC=com
displayName: testADUsr_1
sAMAccountName: testADUsr_1
userPrincipalName: testADUsr_1
userAccountControl: 512

If the comma in the CN(of the dn entry) is escaped, then it successfully creates the user at AD.

dn: CN=testADUsr\,_1,OU=pass_sync,DC=win2k8sync64,DC=com
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: user
cn: testADUsr,_1
sn: testADUsr,_1
uid: testADUsr,_1
givenName: testADUsr_1
distinguishedName: CN=testADUsr_1,OU=pass_sync,DC=win2k8sync64,DC=com
displayName: testADUsr_1
sAMAccountName: testADUsr_1
userPrincipalName: testADUsr_1
userAccountControl: 512

    Branch: master
    Fix Description: When we construct a new AD DN, usually from the value of the
    "cn" attribute in the entry, we need to escape the , and any other special
    characters in the value used in the DN.  We do this by putting double
    quotes around the value, and let slapi_create_dn_string remove the quotes
    and use \ escapes instead.
